Handsets for the upcoming 3G cellphone system can be automatically upgraded by downloading software from the network. But if the software becomes corrupted during the download, the phone can give the network bad information on reception quality, fooling the base station transmitters into sending too much power. This can interfere with other cells and crash the whole network.
Motorola’s fix is for the handset to store reception data before and after any software update (GB 2375687). If the measurements don’t match, the phone shuts down to protect the network.
