Also, I have a related question to the previous problem. If by any chance all solutions fail, obviously what I would have to do is a factory reset. So, when I'm rooted and have CWM installed, is the factory reset done via CWM or the option in the stock ROM?
EDIT: The problem is fixed again. I don't really know what to think anymore
EDIT: And now it works only via Wifi
I can surf via 3G, but Market apps won't sync.
