Applecare screen replacement is a breeze, if you live near an Apple store. Walk into scheduled appointment, hand them your phone and sign your name on their little iPad granting them the permission to repair or replace your device and dealing with payment, and they tell you to come back an hour or two later and pick up your device. I always buy Applecare and have had to replace each of my last iPhones at least once this way, but it's really a no-biggie because it only takes maybe an hour total to drop it off and pick it up, including driving time, once the appointment is scheduled.
