I wonder how long it took them to work this out....
".....but when we take away the battery, take the SIM out of the phone, the signal is no longer there."
I hate to piss on their picnic, but they seem to have invented yet another mobile device that (cue "ta-da" sound) stops working when you remove the battery.
I'd like to see the testing methods that they used to narrow the cause of this behaviour down to their secret antenna technology.
