Taking a page right out of the textbook for Stalking 101, the iPhone Recovery Stick USB stick is capable of recovering any text, call, photo or even website that had been previously deleted from the device. Ironically only compatible with Windows, simply plug both devices into a PC and click the Start option. The rest is handled automatically.
The software included with the iPhone Recovery Stick allows you to easily surf through all of the deleted media that was recovered off of the iPhone in question. You can even download the data onto your hard drive for later viewing. The sneaky, yet most effective way to keep an eye on that special someone.
