How much does it cost to repair a broken iPhone 4 screen?

I dropped my iPhone 4 and the front screen is all messed up. Where can I go and how much does it cost?

A Kiosk at a mall will charge about $80 (i asked about 6 months ago). Ha.

I hear it's cheaper if you do it yourself ($10-20) Youtube: D

At this point an iPhone 4 is only.99 cents brand new for most places if not free. If you don't have an upgrade ask about adding a line or best bet is to call your phone carrier and see what choices you have
