Is there any difference between iPhone 3G and 3gs back cover?
Is there any difference between the back covers for 3g and 3gs?
What i can see there is three different sizes for each model 3g, 8,16 and 3gs, 8,16,and 32 and all of them
iPhone 3g and 3gs have same covers and don't say whether it's s or not. If you're buying with parts in the headphone Jack is universal but battery is different as is dock connector. Not sure if vibrate motor is the same, but should be listed as either 3g or 3gs compatible depending on inclusions- just make sure you order the right one.
