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. Would you get the app so you could see where your significant other has been going?
