I have been extremely fortunate when it comes to Charleston cell phone repair: I HAVEN'T NEEDED ANY REPAIRS! Just suffered the typical freezes - software reboots etc. that most of us have come to expect with our cell phones. HOWEVER - for anyone who has other repair issues you probably are quite aware that repairs at your local carrier are not a featured service....
You can thank Scott at T-Mobile on James Island SC for the following options for cell phone repair - so if you Drop it, Dunk it, Throw it, Smash it, Step on it etc, and suffer some negative repercussions you may want to visit these guys:
