ok, i've read all these posts and i'm still not understanding entirely... I have a mytouch 3g that has a 3.5mm headphone jack on the top.... I want to root the phone and put a custom ROM on it. I watched a friend of mine do this on his lg ally, and it was SUPER EASY.... I on the other hand am having issues... it has 2.2.1. can anyone point me in the direction of a step by step, noob friendly, guide on what i need to do? can i root with 2.2.1? do i need to downgrade? note: i do not have a way to hook my phone to the computer at this time, so a way to do it all over the phone like my friend did with his ally would be AWESOME.
