If you wan’t to get a head start and download iOS 5 for your iPhone 4S before it arrives then download them below. It’s a good idea because it’s a big one, weighing over 700 MB. Holy cow right.
iPhone 4S iOS 5.0 DOWNLOAD for all iPhone 4S models.
So far there is only one download for the iPhone 4S not sure if it’s the same one for all Carriers, but it’s the official download link so it should work. Let me know if it doesn’t please!
