I'm wondering what physically has changed between the CDMA iPhone 4 / GSM iPhone 4 and the new iPhone 4S.
- the placement or number of bands interrupting the metal side case
- micro SIM slot location
- camera and LED opening / placement
- home button
- receiver / front camera / proximity sensor placement
Superficially, the buttons on the 4S seem to align with the CDMA model spacing as opposed to the GSM spacing
I ask to know and for the practical application of people that want to reuse a precision case or protective film are going to find differences. I'm looking for first hand knowledge or reports of people taking a micrometer to the shipping hardware and doing a comparison.
