I'm on the 3.1 beta... and I know the official release is coming soon! I really want to jailbreak my phone now but I'm on 3.1! haha... btw does anyone know if Jailbreak kills all PUSH services?
Push should work fine. Even it is unlocked. The trick is to not "hacktivate" the phone. Borrow an active AT&T sim and activate the phone with that, that will avoid an Push problems.
