Is anyone having issues with their 3rd party apps crashing after syncing the iPhone 3G with their computers? Specifically, I have the old iMac G5 (just before Intel). After syncing, applications that were working fine stop working. When I touch the icon to open them, they open up a blank window and then turn off. This has happened to me twice already and each time, I had to reinstall the apps. It's also made my phone restart suddenly once. Any known solutions?
