My iphone has been working fine then suddenly a few days ago, for no apparent reason, all of my movies and songs vanished and when I go to the About page it says the capacity is only 300mb and I have 103 mb remaining. I haven't synced my iphone in weeks and now when I try to sync it gives me an error saying I do not have enough space. I'm running firmware 1.0.2 unshackled so I'm afraid to do a restore to firmware 1.1.1 because when I click on restore it says it must do an update and restore. I don't want 1.1.1 firmware, especially if it will brick my phone.
