In areas where there is dense transimtter coverage, accuracy can be as
good as 50-60 metres. In the UK, this is about the same level of
accuracy as knowing which postcode you are nearest to. Potentially scary
stuff indeed.

I have heard of cases where criminals have been tracked because they
left their mobile phones on, and the police looked at the phone company
logs. Alibis were broken this way. I have no idea if this level of
accuracy will be available to wireless applications.
