I'm having a problem that I can't fix. When I enter the App Store on the iphone 4 firmware 4.2.1 and select the Featured tab the app crashes. I can select and view the other tabs in the app store except for this one. I've currently restored my phone twice to see if this would fix it but it didn't fix the problem. My phone is not jailbroken during this issue. Can anyone assist me with this problem? Thanks in adavance!
