iPhone 2.0 has been installed early onto my iPhone. It completely restores your iPhone and thus takes a good while to finish updating, a long good while. At one point I thought I might have bricked my iPhone since this isn’t yet the official update (you have to force install it instead of a simple click).
Every time I try to sync the iPhone, it spends nearly 45 minutes backing it up. Every time. Furthermore a few of the apps crash the iPhone, though a simple restart has fixed that issue. Hmmmm.
