You can't. The difference between the iphone 4 and the 4s are hardware based and just software differences.
I see no reason why not. Has your phone provider indicated they no longer support it?
not a 4s but he has a red iphone 4
the iphone 4s stands for 4 speed
the 4 and the 4s are.
The Turtle Webkinz is Faster Than Both the iPhone 4 and iPhone 4S Combined
iPhone 4s has a better cam thinner faster siri
4S
iphone!he has a iphone 4s its awsome! LOL! :)
iPhone 4S
iPhone 4S
take to a iphone store
iPhone 3GS. Then the iPhone 4 and then the iPhone 4S.
There are a lot of sites that sell iphone 4S covers, in my opinion www.ebay.com. Iphone 4 and the iphone 4s are both same size, so you could get an Iphone 4 case too.
