i have iphone 3gs, old bootrom, 3.1.2, with untethered jb done using blackra1n. i had activated the phone using att sim card and then did the jb. now to the mail point about push notifications. 1. it works from time to time, and i get push notifications from ebay, and couple of games 2. it does not work with my work exchange email setup, push is enabled and i get "beep" when the new mail comes in but no notifications i totally understand that i cannot restore and jb and all that stuff, and i dont have my shsh files stored on cydia. so the question is, is there anything that i can do to fix the push notifications issue with my mail, without having to restore thanks in advance.
