Well, I thought the remote app would be really useful for controlling my iTunes from the other room, as I have an Airport Exprese in another room, using AirTunes to stream music. However whenever my iPhone moves over from the regular network to the extended it can no longer communicate with iTunes, and the only way to fix it is to go back to the Airport Extreme network and reregister with the library. It's really annoying, anybody got a fix for this?
