you dont need to hack to unlock it just call tmobile for the unlock code just till them you are a developer.
DONT TRY The 2.0 eclair update will give these options. DONT PHONE!
very good video presentation.
what do you do when it says no disk in the diver?
that happened to me , take ur SD card out , put it in someone elses phone , hook that phone up to the compuder and take out the update and the dreaimg ... then do it all over from step one , put tha SD card in ur phone and press the phone button, menu and power off ..
doesnt let me format my SD card to make it fat32...whats up?
Guys just do the one-click root process. It's much faster and easier for beginners. Although this is the best tutorial for rooting the phone the old fashioned way. This is the way I did it, so thanks again Anthony.

Excellent video, i just might give rooting my g1 a try. Although.. do you have to have a data plan for when you've downgraded and have re-enter the gmail settings for the phone?

try formatting the sd card from within the phone itself. From the mainscreen of your phone, press menu>settings>sd card and phone storage> Format SD Card.
The Downgrade link isnt working!

i am stuckk on rc 29 how do i upgrade because telnet is not workingg!1 help if you couldd plezz!!!
OK so if anyone else had the same problem as I did here's the solution. Check with T-mobile to ensure your data service still exists, if it is somehow missing after the downgrade just tell them to sign you up for the data service. You should be back up and running within minutes if not I don't have the answer
Did you remember to mount the phone to the computer? Cuz I had the same problem. I just forgot to hit mount.
Do I need the data package on my G1 to root it?
i was talking to a t-mobile tech about my iPhone getting a sidekick plan (and i did) and that is what he told me they do with there phones. i dont know if that polacy has changed but you can also do it for $11 if you dont feel comfortable hacking, but the G1 is pretty straight foreword
what can you do on a rooted g1 anyway
@macalotczar yes but you have to use android sdk and install the correct motoroal usb drivers throught the adb interface then using the cmd module to then acces it send me a message if u want me to describingly tell u
