OK so I just got the Mytouch 3G from Tmobile USA and had a few questions before I rooted the phone.One question is when I do root which custom ROMs would this community recommend?Another would be if for any reason I don't like my phone rooted can I go back from 1.5 to 1.6?I have to downgrade from 1.6 to 1.5 anyway can that be reversed or is that why you back up your recovery image so you can get back to stock firmware?Any help on this would be awesome!Thanks!
