Hello, just bought an iPhone 3GS yesterday, version 3.0.1. Jailbroke (but didn't unlock) it using redsnow. Push worked for the couple hours I had the phone before jailbreaking, now that I've jailbroken it push doesn't work. Granted, I've only been at home where I only have wifi reception, not cellular, and so I haven't tested it off of AT&T's network, but I really doubt this is the problem. How can i fix this?
