Try *this* on your Smartphone!

In my previous post, I ranted about my Palm Pre eating some important pictures I had taken...

Well, I went looking for them in the Pre's flash memory, using photorec(1).

I simply plugged my Pre into my Ubuntu laptop, tapped the Pre's screen selecting USB Drive, and the Pre shows up as /dev/sdc.

Next I ran
sudo photorec

I worked my way through a few options, and scanned the entire 8GB disk, which took ~20 minutes.

I actually found my missing pictures!

Moreover, photorec recovered several megabytes of C, C++, Javascript, and Shell source code!

I'm not going to post it here, as it's not my copyright and I don't see an open source license, but if you're curious what's lingering around on your SmartPhone's backing disk, give photorec a try ;-)

A Palm Pre Rant

While I'm usually a rather positive person, this post will not be, so beware...

I use a Palm Pre as my primary phone. I previously wrote about about my Pre and my G1. I love that it's running Linux (WebOS), and I really like many things about the phone and OS. But there's a ton of little things that are really starting to drive me nuts about it.

Every time Palm forces an upgrade of my OS, several things break. Most recently, the 1.4 upgrade broke Terminal and MyTether -- two of my most frequently used applications. Moreover, what's with forcing a user to upgrade? I was so much happier with the old version.

The Touchstone charging station is a complete waste of money. I thought it was pretty cool that it uses magnetic induction to "wirelessly" charge the phone. But the software integration with it is absolutely terrible. It's simply unusable on the nightstand next to the bed, since the backlight is forced on (with no way to disable), so bright as to disturb your sleep. Other times, it appeared to be charging, but wasn't actually doing so, and the phone just slowly committed suicide. It's $70, doesn't include a USB cable, and doesn't work very well at all. Buy yourself a $5 retractable microUSB cable and skip the Touchstone entirely.

I love that the headphones jack is a standard 1/8" plug. But about half the time I use it, the sensor that detects whether it has a plug in it or not gets "stuck", and I spend the next 20-30 minutes plugging and unplugging the 1/8" head phones plug into the slot until I can by chance get the friggin' sensor to reset. This is a giant pile of suck that renders your phone unusable until you can get the sensor to reset. I pray that I'm never in an emergency situation where I need my phone and this happens :-/

And finally, it just recently "ate" a bunch of pictures that I had taken of some flipcharts we were using to take notes at an Ubuntu Server sprint. Yeesh. So I can't really even trust it to save the pictures that I take.

So my take on the Pre after ~6 months, from best to worst...

• Linux -- awesome
• Real keyboard -- awesome
• App store -- decent, but less than Android or iPhone
  
• Flip-mechanics -- feels kind of cheap
• OS graphics/effects -- pretty nice, I guess
• OS stability -- okay-ish
• OS speed -- kinda slow for some things
  
• Battery life -- not so great (less than 24 hours)
  
• Sprint forcing OS upgrade -- highly undesired
• Touchstone -- waste of money, skip it entirely
  
• Headphone jack issue -- should force a recall of the devices, IMHO
• Arbitrarily deleting pictures -- WTF
  

So I guess I'm starting to look for another smart phone. I don't think I'm in love with the Pre. We were never married, of course. Just courting. And in the end, I don't think we're meant for one another. She's just a little bit unstable and immature for me :-)

How long until I can buy a mass market smartphone running Ubuntu? Is that too much to ask? ;-)

Palm Pre (WebOS) vs. HTC G1 (Android)

I blogged a couple of weeks ago about my new Palm Pre. I've been using it for over a month now, and I have a few more thoughts to share. But also, I won an HTC G1 from Qualcomm at the Linux Plumbers Conference in Portland. This was fortuitous, as I was quite interested in this device too.

I thought I would provide a comparison of the two devices, based on my experiences...

Network

Originally, I bought the Palm Pre because the G1 was not available on the Sprint network. While Sprint has disappointed and frustrated me more than once in the past 10 years that I have been a customer, their coverage in the USA is pretty good, and the unlimited data plans have served me well. I have not been under a contract in over 9 years, and don't intend on getting into a contract again with Sprint or any other carrier. I can use the Palm Pre in most of the USA, Canada, Mexico, and South America. But on the down side, I cannot use it in Europe or Asia.

The G1, on the other hand, takes a SIM card, and can be used on most any GSM network. I won a developer version of the G1, so it was unlocked by default. I simply borrowed a SIM card from a friend for 2 minutes, long enough to access the data network to login to my Google account and register the phone. After doing this, I gave Ted his SIM back, and my phone was functional as a stand alone "computer".

As it turns out, I do actually have a pre-paid SIM card from eKit.com, which I use in an ancient Siemens C60 phone when I'm traveling in Europe. While I have to use a second cell phone, I do prefer the prepaid route, as it's just too easy to spend several hundred dollars on your native carrier when traveling. So I was able to pop my eKit SIM card into my G1, and place and receive calls. I don't have a data plan on that SIM yet, so I wasn't able to test that.

HINT: To place a call using the eKit SIM on the G1, I needed to prepend *126* on the number I want to dial, and append #.

Connectivity

Both phones have WiFi and Bluetooth wireless connectivity, which is quite nice for large downloads. This, of course, absolutely drains the battery.

I mostly use the G1 as a WiFi device right now, since it's not connected to a cell service. It's great for browsing the web or using the various applications available on the platform (more about that below).

Most importantly, though, I have been able to make and receive calls over WiFi. There are many other blog posts floating around explaining how to do this. But basically I needed to:

1. Apply for and receive a Google Voice account
2. Register and activate a Gizmo5 account
3. Add my Gizmo5 number to my Google Voice account
4. Download and install SIP Droid on my G1
5. Enter Gizmo5 username/password, and proxy01.sipphone.com as the server
6. Enable WiFi, and wait for SIP Droid to authenticate (this part is buggy, as far as I can tell)

I have been able to do this well, from my home WiFi network. I'm looking forward to trying this abroad.

Tethering

The Palm Pre is a dream come true for anyone interested in tethering (though Sprint may apply additional charges to your account). With great pain, I have managed to tether using my last 3 Palm Treo's. With the Palm Pre and Ubuntu, however, it's ridiculously easy. I simply needed to root the device, and install My Tether. When I enable USB tethering, Ubuntu's Network Manager detects a new usb0 device, and grabs an address over DHCP. My practical download rate is an extremely respectable 150KB/s. I was able to maintain connectivity while riding passenger in a car over 7 hours and 450 miles between Austin, Texas and Baton Rouge, Louisiana last Thursday.

I have not been able to test the same operation on the G1 yet.

Console Access

I love that I can get a Linux shell on both of these devices. They both have small terminal applications accessible through the phone interface, but, of course, these keyboards are tiny and clumsy to do anything serious. Using vi, for instance, is a nightmare. But it's trivial to access either device through a terminal application from my Ubuntu desktop over the USB connection, and use a real keyboard.

I was able to install an SSH server on the Palm Pre, which is really nice, because I can now SSH directly to it, when it's connected on my WiFi network. No need to deal with cables or special terminal applications on my desktop.

Also, I like that I have root on the Palm Pre, and that it's possible to install packages from the command line. I have not yet obtained root on the G1. It looks slightly more difficult. I'll give that a shot soon.

Physical Device

The Pre is significantly smaller than the G1. It's easily the smallest cell phone I have ever owned, which is truly remarkable when you consider how powerful the device actually is.

I'm not a big fan of the little curve on the G1 toward the bottom. I think a completely flat device would be a bit more sleek.

However, the G1 feels like a very well made device. I like that you rotate the device sideways, when using the keyboard. The QWERTY keyboard is huge compared to any of the Palm or Blackberry devices. It's actually quite usable. Big keys, decent spacing. The hinge mechanism feels very sturdy, solid. I like the way it snaps into place, with no wiggle or play. I also really like the roller ball. There's some times I just don't want to touch my screen. Or I don't want someone else touching my screen. The roller ball, with the ability to go up/down/left/right and select is an excellent design feature.

Unfortunately, I think the physical design of the Palm Pre is its weakest point. The hinge feels very flimsy. It wiggles and has way too much play. It feels like it's about to break pretty much any time you're opening or closing it. It slides vertically, so, the screen is in portrait mode if you're using the keyboard. Most web pages and applications, it seems, perform better in landscape mode. The keyboard is also very small. The buttons don't rise as much as on the older Treos, and it takes a little while to get used to. I also very much hate that there is no up/down/left/right/select button. Everything has to be done with the keyboard and on screen gestures. This can be very painful for some applications, in my opinion. I'm really hoping the Pre is a "preview" of better hardware to come...

Ports

I love the fact that the G1's charging/syncing port is a very standard mini USB connection. I probably have 10 of these cables floating around, and it's fairly likely that if I don't, someone near me does, that I can borrow for a few minutes of juice.

The Palm Pre uses a strange little micro USB connector. Of course, I didn't have any of these cables, and one cable isn't going to cut it. So yes, I had to buy an extra cable or two (at $25 each). Disappointing. But, still, it's USB, and can charge nearly anywhere these days.

On the flip side, the Palm Pre has a standard 1/8" stereo jack. I can use my Palm Pre to play my MP3s or stream Pandora or internet radio stations directly to my stereo receiver, or to the auxiliary input in the car. I actually streamed 4 hours of the Saints/Dolphins football game on Sunday, driving back to Austin from New Orleans, pulling internet radio over the cell network and output to the car stereo. That was really cool ;-) And the Saints put together an amazing come-from-behind victory!

But the G1 uses the USB port to output sound too, which is odd. It came with a pair of stereo headphones, but I'll presumably need some sort of an adapter to send this signal to the car stereo.

It's disappointing that neither device quite gets the connection ports right. I want the Palm Pre's 1/8" audio jack, and the G1's standard micro USB jack in the same device. Is that too much to ask?

Storage

The Palm Pre ships with 8GB of storage built-in, but no expansion slot. The G1, on the other hand, has a microSD expansion slot. It was able to read my 16GB microSD card.

Seriously, Palm... This is really disappointing. The card and card reader are tiny. This omission is so obvious I conclude that this design decision is to ensure that Pre owners must upgrade their hardware to obtain more storage in the near future. I'm afraid this might well backfire on Palm, though.

My music collection has been under 80GB for almost 5 years now. At the rate that microSD cards are growing, I expect to buy a 128GB microSD card in the near future, and would hope to be able to carry my entire music collection on my mobile device. Unfortunately, it doesn't appear that the Pre will be that device...

Operating System

I'll probably devote an entire post to WebOS vs. Android, so I'll just hit the highlights here...

Both are Linux, Linux, Linux. That's just pure awesome. I've said it before... We have been hearing about Linux cell phones in the USA for years now, and that day is finally here.

Terminals on both--that's great. Both OSes are very stable and responsive. They both take a long time to boot, but the uptime has been excellent. I rarely need to reboot either of them.

The icons and effects on WebOS are perhaps a little sexier, but that's among the least of my concerns. I do find WebOS far more intuitive than Android. Finding applications, menus, settings, etc., is easier on WebOS.

Multi-tasking on WebOS is simply amazing. Launch program after program, moving it to the side, and bringing it back when you need it. It's ALT-TAB for your phone. I love it.

I see a lot of promise in both operating systems.

Upgrades

I have managed to upgrade the OS on both devices. The Palm Pre was very simple. Much like Ubuntu, I just checked for updates available, and applied those. I did so over the WiFi which was a bit quicker than over the cell network. Unlike Ubuntu, I couldn't easily see what was being updated. I'd like to find the equivalent of the ubuntu-changes mailing lists for WebOS...

Since I have the developer version of the G1, I was able to upgrade my OS to Android 1.5 (and I see that 1.6 is now available too). The upgrade procedure was straightforward, though definitely intended for developers, as you had to use the SDK to upload a new binary to the phone, and reboot into a special mode with an odd key combination. That said, this is fun for me, so I'm enjoying the G1 from the developer angle.

Applications

Android has been around a bit longer, and it seems, at least at this point, to have a larger developer community. The Android "Market" has more applications than the WebOS "App Catalog", just from a numbers perspective. But there are a lot of duplicates. I have found almost all of the key applications I need for my Pre (with the notable exception of a SIP client, though it appears that one is under development).

It's clear that Apple's iPhone has a tremendous advantage on the App Store front. I think the rest of the cell phone OS market would do well to converge a bit, and confront Apple together.

That said, I would really, really love to have access to Ubuntu's archive of 20,000+ applications on my Linux devices. It seems like such a rich resource to tap into. Most of these devices have ARM processors, and we're actively working on Ubuntu's ARM story. With the 8GB of space on my Palm Pre, I could easily apt-get install most of the applications I carry around on my desktop. I'd like to think we're not too, too far away from that day...

Accessories

I don't collect a lot of accessories. Actually, I don't have any accessories for the G1.

I did buy 2 Palm Touchstones, on the premise that this technology was pretty cool. It's a little hockey puck sized "wireless charger". It uses magnetic induction to charge the Pre. When it works, anyway. I've run into a number of problems, most of which seem to be software. It seems that the software side doesn't always detect that the phone is sitting on the Touchstone. More importantly, it seems that if the software doesn't detect that it's on the charger, it doesn't start charging. I have run my Pre completely out of battery more than once now, and when this happens, the Touchstone won't do you any good. You have to plug into the USB. This creates a vicious cycle, if you put the Pre on the Touchstone, but it doesn't charge, it runs out of battery, and then you have to plug into the USB to get it usable again. I must say that I'm extremely disappointed with the Touchstone. I think I'm going to try and return them. This issues might be fixed in a software update, I suppose, but right now, the Touchstone is not worth the already-overpriced $70 tag.

Conclusion

I'm definitely enjoying both devices. Linux on the phone has a promising future. WiFi, QWERTY keyboards, App Stores, these are all great things.

The Palm Pre would be the perfect device if it had:

• roller ball for up/down/left/right/select
• removable microSD card slot
• sturdier sliding mechanism
• standard mini USB connector
• decent SIP client for VOIP calls
• longer battery life
  

The G1 would be the perfect device if it:

• were slightly smaller, lighter
  
• were available on the Sprint network
• had a stereo audio output
• had longer battery life

Byobu on a Palm Pre

Having owned Palm Treos 600, 650, and 755p, I finally bought a used Palm Pre off of Craigs List earlier today. And although I've had the phone less than 24 hours, I already love it!

Following a couple of guides online, I obtained root on the device without a problem. This is where the real fun begins...

I was absolutely delighted to find that GNU screen is installed by default on the device! Which, of course, means that byobu should run too ;-)

I had to fix a few things in byobu, since I had never tested it on ARM, or inside of busybox, but it's working quite well! See this screenshot:


So within the first 12 hours of owning this little miracle, I've managed to:

• sync all of my contacts and calendars from Gmail and Facebook
  
• obtain a root shell
• run screen
• install and run byobu (using byobu-export from the unreleased byobu-2.33)
• install and run an ssh server
• ssh to the device
• tether (working perfectly with Ubuntu, writing this blogpost tethered right now)
• actually lower my monthly service plan with Sprint
• sign no contract since I bought used via CraigsList
  

But the best part... Real Linux, with a root shell, running on my phone. I've been waiting for this day for over 10 years. I'm choking back tears. Wow.
