Hello all. I'm new here and not afraid to admit that I'm a bit of a dummy when it comes to the inner workings of my android device, so please be nice! I recently bought a sim-free unblocked HTC One S handset over the internet. I wasn't aware that it was coming from Hong Kong, but hey ho. When it arrived I was met with some features/apps that confused the hell out of me. When I first turned it on there was a screen with ClockworkMod options. With no idea what this was I swiftly rebooted and arrived at a familiar looking homescreen. In my app drawer I discovered AnZhi (which appears to be an Asian equivalent of Google Play Store), Root Explorer and SuperSU. Now, I have a very vague knowledge of rooting (i.e. I know it exists), but I am completely oblivious to what it means. After inserting my Vodafone sim card the phone seems to be working fine, except it isn't detecting my location or picking up weather details. It would also appears that HTC Sense isn't syncing. I'm assuming that this is something to do with the fact that the phone has been rooted (whatever that means!), but I really don't know. So, after all my waffling above, I suppose what I'm really asking for here is some basic 'rooting for idiots' type help. What does it mean to me? Can I unroot and resore factory settings or will this pose a problem (remember the device has come over from Hong Kong - I'm in the UK)? Thanks in advance!
