Guess Bluetooth isn't as short-ranged as I thought.
My neighbour has a couple of guys who turn up from time to time to work on his garden. Last time they were here, as I pulled up to the house, I discovered one of them had a Nokia 7610 called Attila 7610. This was because it kept trying to persuade me to accept a file. I quickly realised this was the Carib virus, told the guy and even printed off instructions from the McAfee and Symantec sites for its removal.
This afternoon, as I was working in the loft, yep, got constant stream of messages on the 6680 asking me to accept a file from Attila 7610. Sigh. However, that's an unexpectedly impressive range on that 7610!
