I have the same issues with signal drops and canals cutting out. I'm with O2. Tried all te resetting to 2 g etc. no change. Signal drops out for no reason. I'm 500 meters from the O2 mast. Went to the shop today they replaced my sim card. Still same issues so must be a faulty phone.great phone but useless if it does not do what it's meant to...Will keep that in mind, saves restarting the device.
