Apps maybe. I wouldn't trust TB with system things, like contacts. Especially since i was transitioning from 2.3.6 to 4.2.2. So I just used something (forgot which it was) that exports contacts/call logs/SMSs I think as XML or some other "plain/neutral" format and imported it. Sadly, the WiFi didn't rearlly work (it was another app, though) but everything else went flawless
TiBu actually gives you the option to restore files as an XML file OR some other format that's quicker but less compatible.
@Big bowei: That sticker looks nice!
Well schiit, I think I've definitely had better weeks than this one... >.>
