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. It's a conspiracy theorists worst nightmare.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.

I'm personally not too worried about this since I don't have any secret rendezvous that I need to keep hidden, but it does seem crooked that they tried to hide it.
