I tried posting this on the iPhone forum but didnt find the answer, so Im hoping that maybe someone here has an idea. My son has an iPhone 3GS jailbroken running 6.1. Imessage was working just fine until mid June then for what ever reason he lost wifi connection. I was able to get that going again but I can't get imessage to activate. I've tried doing a hard reset several times, resetting network connections but no luck. He hasn't downloaded anything new from cydia in several months now so that wouldn't be the issue either. I did read that apple had some kind of issue with imessage in June so maybe it's related to that? Thanks for any ideas.
