does it have any yellowing effects or noticeable cracks? after time?
There are already a couple extensive threads about this issue...but no, there are no issues with the white iP4.
It is not exposed to air because it's under the glass. Therefore it will not change to yellow on it's own. 🙄
How about the plastic trim that surrounds the glass?
Good point. 😱
That'd be a pretty cool iPhone. White with yellow trim. 😉
