I've had the Verizon iPhone 5 for 5 weeks now and all throughout yesterday to today, the Power/Lock/Sleep button doesn't work as good or has been unresponsive. i've tried using it with and without a case(i have the griffin reveal case). anyone else have this issue? what have you done to resolve it? shoot! hopefully i won't have to send it in for a replacement...i'm from hawaii but currently in california for 2 more days. if i get a chance to get to a nearest genius bar to have it checked, hell hopefully i get it fixed before i go back home.
