Hey folks, Recently, I noticed that I am unable to receive push notifications over AT&T's 3G network. As soon as I connect to a Wi-fi network, I sometimes get a flood of notifications (Facebook, Words with Friends, news articles, etc). In addition, I cannot send my iPhone messages using Find My iPhone, or even locate it, unless it's on Wi-fi (all other devices on the same account work). I downloaded the free app iPusher, and it only works on Wi-fi. Last month, I jailbroke for the first time, mainly for MobileNotifier. I backed up my iPhone today and restored it from that backup, and push notifications still didn't work. However, when I wiped it but didn't restore from a backup, they worked. Unfortunately, this really isn't an option because I'd lose all of my app data. I jailbroke it again and tried Push Doctor, but it didn't help. I'm using an iPhone 4 and running iOS 4.3.3. Cellular data is working fine in Safari, Facebook, etc, as are SMS messages. Any help? Thanks!
