Hey. I have an original iPhone, unlocked and jailbroken way back on 1.1.4 or so. It's currently running 2.1. I'm wondering - I don't use any of the unofficial applications, I'm using it on the same network (o2) as it's uh, supposed to be on... would it be safe to just let iTunes grab the 2.2 update and future updates? Or is that sure to brick it?
