my one year old 3GS has the problem with every single app crashing when opening them after upgrading to 5.0. I have rebooted the phone and the problem remains. I didn't have this problem on an iPhone 4 and even waited two weeks to see how the iPhone 4 worked before doing the 3GS. I still have another 3GS that I won't upgrade now after seeing these 3GS problems. Any ideas?
