As title says, I've just moved to a Nexus i9250 after years with iPhones. Love the phone. I don't know anything about Android, so wanted to ask re. updating from 4.1.2, which was on the phone when I bought it, to 4.2. Oddly (or maybe not) I was getting a message every time I powered on the phone or woke it from sleep, that there was an Update to install. I always declined, as I didn't have time to sit down and do the update right. Suddenly, though, the message doesn't appear any more, though now I would like to update! Ain't it always the way? Under system info it says the phone is up to date. When I was getting the message I thought the update would be automatic, in iPhone style. Wrong? Do I need to root the phone (jailbreak?) and then do the update? Is it always a modded update, or are there "official" ones you can download and install without doing anything to firmware? Probably a bunch of dumb questions, but any help greatly appreciated.
