I tested the Ihome in the apple store. Although it charges the iphone and works, it askes to go into airplane mode. If its fully compatible it should not ask to do that. Not sure if anything would happen, but I did have a friend fry her iphone in a dock that was from an older ipod. She didnt put it in airplane mode when it asked and got a call, her iphone went nuts. Fortunetly after a reset it still works, but its never been right since. Constantly having issues with it.
