Build your own mobile phone
Don't you just love it. Building your own mobile phone is now becoming a popular hobbyist event. In fact, it isn't as difficult as may be imagined. Why is it good for forensic... a unique fingerprint of activity, of course.
Credit to the Tuxphone guys putting this together. Couldn't see the point though of buying surplus components when you can pick up second-hand handsets dirt cheap...and rip them apart.
