Chosen Solution

im an aspiring photographer and would love to just use iphone 4s camera to take pictures and make videos. i have an iphone 4, but was wondering if its posible to have the camera replaced with the iphone 4s..

No the 4 and 4S have completely different flex cable and flex cable connector on logic boards. So the cameras are not compatible and not interchangeable. The pin numbers are different. This was discussed on these forums about 1 week ago.
