I just rooted my phone and I'm not in the know with how to install roms, however most of the rom sites indicate how to install. Most of the roms I've visited recommend doing a data wipe and a cache wipe. Is this something I have to do every time I want to install a rom? I just did a factory reset for the 2.2 OTA and, quite frankly, it was a pain in the butt to get my phone back to how I had it. So, am I going to have to do a factory reset every time i want to try a rom?
