Hey guys, I need some help here.. I have an iPhone 4 (not jailbroken) and I have problems downloading apps from Appstore. Each time I try to download something, the icon will indicate "Waiting" and even after an hour, it remains the same. I have also tried using my home wifi and a friend's wifi but the problem persists. It started after one of my app payment failed, though it has since been resolved. I have tried restarting my iPhone and all, but nothing seems to work. Is anyone experiencing the same problem? Any help would be greatly appreciated.
