I have an old G1 and want to start using a myTouch 3G that i got from someone. I dont have a data plan on T-mobile but i heard that if you can root it and somehow access the WiFi you can activate it without a data plan. so im trying to figure out how to make that work. can anyone help me? oh and i downloaded Android SDK and extracted it to the C:\AndroidSDK folder like in the video, and when opened cmd prompt and typed the necessary commands, every single command i typed was "unrecognizable" or didnt exist. any ideas? i cant access the phone at all since i dont have it activated i cant even get to the home screen. and i dont know anyone with a android phone that i can swap out sims so any help would be GREAT! thank u.
