First comment on the replies to this thread is, "I'd never ever buy a BT branded phone - now that is asking for trouble, ie overheating/over charging batteries", better to still with Panasonic I've found.
At least most of the "Microsoft" people that phone me up have British names, pity they don't sound very British! I keep trying to remember to change into "very old woman" mode, and try to have a "nice" chat with them, but so far I've failed and tell them to F--k off, which usually ends up with a response like "would you talk to your father like that?" to which I reply "no and he is dead" then they start probably swearing - and not in any British language I've heard before, w#nkers!
