The Reason I Don’t Own An iPhone
Security experts Peter Warden and Alasdair Allen have made a startling discovery about Apple's iPhone and 3G iPad: The devices secretly track and record your location.
Apparently, this has been going on for 10 months, despite the fact that Apple has never previously disclosed that they keep a record of all their iPhone users whereabouts.
Warden and Allen have also developed a free app that allows you to access this information yourself, so you can see displayed on a map all the places you've been to with your iPhone since June.
Of course, this means anyone who gets a hold of your iPhone -- in particular a jealous significant other -- can also easily uncover this information.
So far no comment from Apple on this disclosure.
