Got an iPhone in your pocket? Then you might be storing even more personal information than you realize.

And some of it could be used against you if you're ever charged with a crime.

A burgeoning field of forensic study deals with iPhones specifically because of their popularity, the demographics of those who own them and what the phone's technology records during its use.

Law-enforcement experts said iPhone technology records a wealth of information that can be tapped more easily than BlackBerry and Droid devices to help police learn where you've been, what you were doing there and whether you've got something to hide.

"Very, very few people have any idea how to actually remove data from their phone," said Sam Brothers, a cell-phone forensic researcher with U.S. Customs and Border Protection who teaches law-enforcement agents how to retrieve information from iPhones in criminal cases.
