I have an old iPhone 3. Yesterday morning, I restarted it and after I did, one of my game apps (Farkle Live) stopped working. It just won't launch. I tried to uninstall and reinstall it but when I tried, I got a message that the app requires iOS 4.3. I have iOS 4.2.1. I plugged in and tried to sync and update but was told that I have the most up-to-date version of the OS. So if 4.2.1 is the most current version according to iTunes, what do I do now? Is it possible that the app is no longer compatible with the older iPhones? I've e-mailed the app customer support and am waiting to hear back from them.
