Fixing corrupted icons
Here is what happened. I purchased a third party app. It worked (and still does) and the icon looked fine. A few days later, I received a phone call on the iPhone, but I didn't answer. I let it go to voicemail. For some odd reason, my iPhone froze after this on the "answer/decline" screen of the phone call. It just froze there and I basically had to force shut and restate the iPhone (which wasn't as easy as I thought it would be). After it restarted, everything was fine except for that one icon. A dark blue band appeared across the top of it. Everything else was fine and the app still worked perfectly. I tried deleting the app from the phone and resyncing with iTunes on my computer, but it came back looking exactly the same way.
How can I get it to look right? I can't delete it from both the phone and iTunes because then I will have to pay for it again.
