Samsung BlackJack II

The Samsung BlackJack II is equipped with a SiRF III GPS receiver. Unfortunately, the GPS hardware is locked and will only work with the bundled Telenav software. There is a GPS intermediary driver (GPSID) that Microsoft uses to communicate between the GPS hardware and the applications that use the hardware. The GPSID is by default configured to work only with the Telenav software and Windows Live Search.

Unlocking the BlackJack II is a simple process. Simply insert a T-Mobile SIM card (or any other SIM card). When it says the card is not recognized punch in your unlock code and hit OK. Your phone should now be unlocked. Unlock codes can be acquired from AT&T for free or from any number of sources on line for a fee.
