Those of you anxiously awaiting the release of the BlackBerry 8820 on AT&T may not be getting everything that you expected. BlackBerry Cool is reporting that although the BlackBerry 8820 will have GPS, AT&T has been successful in locking it down so that it only works with TeleNav… at an additional cost of course.

This news comes just after a BGR tipster rumored that the Wi-Fi would be locked down unless you buy a data plan.

Why is AT&T trying to lock down the 8820 tighter that Verizon locks up everything? “The carrier didn’t’ want to launch a device that would seem superior (or be competitive) to the iPhone.”

Research in Motion is not happy at all with the decision but backed down when AT&T threatened not to purchase the 8820 or any future BlackBerry devices if their demands weren’t met.
