MioPocket (MEE-oh-pok-it) is an "unlock" for GPS devices (aka PNAs) running Windows CE. Such devices almost always boot into the manufacturer's software with no way to exit it, meaning that you cannot run any other software; i.e. the device is "locked." Unlocking your device allows you to use it for far more than the manufacturer intended (ex. for music, movies, appointments, other navigation apps, etc.) and more like a PDA. MioPocket is the most-packed and most-fully-featured unlock for PNAs available and is free and legal to use, as it consists 100% of freely-distributable content. What MioPocket is not is a replacement for MioMap, Mobile Navigator or any other OEM navigation software. It is just a frontend from which you may launch the navigation software that came with your device or that you purchase separately.
