A few months ago I began toying with the idea of hacking Android onto a WinMo handset before discovered how inexpensive T-Mobile G1's were on Craigslist. Someone in a city 2 hours from my home had a G1 with a cracked screen for $40. I offered him $20 because it was so far away. The seller accepted and offered to deliver it to me! Score!
Upon receiving it, I found that while the digitizer was destroyed, it still worked. I immediately obtained an unlock code from T-Mobile, slapped in my AT&T SIM card, and flashed the phone to Cyanogenmod 6 RC2. After the first boot I immediately shut of data: I don't have or want a data plan. A few issues later, CM6 Stable was released and all the bugs were squashed.
Now, I'm in the process of replacing the digitizer, which I purchased for $30 on eBay.
I'm stoked to be rocking an Android 2.2 phone that I paid $20 + $30 for! On top of that, I weaseled my way out of a data plan, which saves me another $30 a month. WiFi is plentiful, so I can perform most functions except things that require data on the move, such as navigation.
Digitizer swap results coming soon.
