Ok, got a few questions... My phone is a 3 branded one, running 2.1. 2.2 does not seem to be available as an update... I want 2.2 both to get a proper lock feature and also to stop it continually running out of space by moving apps to the SD card. Firstly, does anyone know if there's a release date for 2.2 for it? If it's soon I guess I'll probably just bear it until then... If not... then I guess I need to do it myself... Does anyone genuinely know if doing so will void the warranty or not? Then - how do I back up all my data, applications and widgets?, and I guess there must be a guide somewhere but I can't find it >.> - how do I upgrade it to 2.2, and is it reversible to get it back to the original firmware if I need to? Thanks.
