I just rooted the OTA 2.2 and installed Titanium backup, ROM Manager, Busy Box and other root apps. I backed up my current ROM (the OTA) and I am ready to start with my first ROM. My question is, do I need to do a wipe since I am coming from the OTA 2.2 or can I get away with it since I am going 2.2 to 2.2. I have read that about ROMS but not to sure about with the official OTA. Thanks.
