My wife and I have 3g iphones, both with rubberized protective sleeves (hers is DLO, mine InCase). I was checking out the Griffin Powerdock2 charging stand for two iphones, and found that if you don't insert any of the cradle adapters the iphones will rest on the charger and stay upright. However, there's really nothing directly supporting the phone other than the charger clip. I'm wondering if this could cause problems like a warped charger socket or even worse a cracked housing on the phone eventually. Has anyone else tried using the powerdock this way with their iphone? Thanks.
