I have an iPhone 3G that I recently purchased used from someone. The seller had reactivated it on AT&T before selling it to me, after which I used redsn0w 0.8 to jailbreak & unlock. I figured that in the process, the key would be erased that makes push possible, but this morning I received an AP alert!

I'd love to be able to preserve my push capability once the Pwnage folks figure out how to handle version 3.1 of the firmware, but would that be possible?
