I am having trouble updating my 3GS to iOS 4.3.5. When I plug my iPhone into my iMAC G5 (pre i sight camera) iTunes opens fine but it begins to back up the phone. Then when that is done I click the update button to update the iPhone OS from 4.1 to 4.3.5, iTunes pops up a window stating that the iTunes software 9.2 is up to date and it does not update the phone. Aren't they different? Is the 3GS incompatible with the new iOS? The phone still works fine and iTunes does as well except for it always backing up the phone instead of just syncing with it. Any tips? Or is my gear just too old and I have to just deal with it until I feel like shelling out moolah for new MAC and iPhone?
Thanks
