If you are careful and have the right tools it can be done without any problems.

or you can pay a repair shop $50 - 75 (plus the cost of the screen) to do it for you.

Reporting iphone as lost, selling it, consequences? A friend of mine just bought the iphone 4s and wanted to know if she reported it as lost and sold it to someone who wanted to activate it, what would happen. She has insurance and was thinking she would get a new iphone, but what would happen to the one sold if it was activated at verizon? Would verizon realize it was the lost phone?
