I have a friend who was running the iOS5 Beta on his iPhone4 GSM. He's trying to go back to 4.3.3. However, when he tries to reload his phone with the back up he created while on iOS5 it won't load onto 4.3.3. He is running the iTunes 10.5 Beta. It is my understanding that the iOS5 has some issues going back to 4 because of an update to the beta. I was hoping someone might have some input to get around this complication. He lost his older backups because his computer crapped out on him so those aren't an option. Thanks.
