the 4 and the 4s are.
they are actually the same size!
Yes, they have almost exactly the same dimensions, but the 4S is a bit heavier.
Yes, the iPhone 4 and 4s models are the same size so all cases and screen protectors will fit the same.
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.
No it is the same shape as the iPhone 4!
They are the same thickness.
It depends. If the iPhone 4 case is for the GSM model (AT&T) then you can put it on, but the ringer slide button will be partially obscured. If the case is for CDMA models (Verizon) then yes, it will fit because when Apple made the Verizon iPhone 4 they upgraded it to be slightly different, and that is the shape all iPhone 4S's are now. iPhone 4 are very similar in shape with iPhone 4S. If you really want, you can put the iPhone 4S phone into a iPhone 4S case. but it may seems no good in apperance, as they are not exactly same.
The iphone 4s desigh as same as iphone 4, so you needn't worry about that ,my girl friend's iphone 4s use my iphone 4 case (buy form 708buy.com) all the time, I prove the iphone 4 case is fit to 4s
No, the big issue is even if my iphone 4 case fit my newer iphone 4S the holes/ports aren't in exactly the same places or designed to be exactly the same...there's execeptions but an aggravation to find.
the iphone 4s stands for 4 speed
not a 4s but he has a red iphone 4
Same size as the iPhone 4's (9 cm aka. 3.5 inches)
