I'm holding out for the official 3 Mobile 2.1 upgrade, but I was surprised to find that as part of the process - when it eventually arrives! - the phone will do a factory reset. I'm pretty sure that other carriers didn't force a hard reset, but hey ho, cest la vie. Anyway, could anyone post me an idiot's guide to what I need to back up, and how I go about it? With regard to contacts everything's Gmail and there are no contacts stored on the phone. Thanks in advance.
