Can anyone venture a guess as to where the physical location of the GPS antenna in the droid Eris is located? I want to use the phone to track me while I swim. The phone will be in a water proof bag but I am wondering which way I should orient the phone in the safety bouy for the best signal. Most of the phone will be above water but probably a half inch would be below the water. Obviously, I want the GPS antenna to be above water. Does anyone know where the GPS antenna is located inside the Eris?
