Hey, recently i had been having problems receiving push gmail messages through exchange on my jailbroken iphone 4, so decided to do a clean restore via itunes. I decided to put everything back on my device stage by stage to see if I could isolate the problem, as push was working on restore. It kept working until I installed AppSync for ios5+ at which point push stopped. I then uninstalled and push started working again almost as if magic. I tried googling for any known conflicts between appsync and push but couldnt see anything. However hotmail via exchange still works, I only seem to be experiencing this with gmail. Weird, right? Perhaps i am just an isolated case here, who knows. Also I am not using Appsync to pirate apps, only to trial apps before I purchase them.
