Big thanks to our friends at BBcool for breaking this shocking piece of news...
An inside source at AT&T has brought word that the US carrier has been successful in their attempt to lock down the GPS functionality in their upcoming BlackBerry 8820. The only piece of 3rd party software that will be given the privilege to function is Telenav.
The reason AT&T chose to do this? Apparently AT&T doesn't want to launch a device that would be superior to the iPhone. Think about it - with Wi-Fi, GPS, BlackBerry's killer push email and subsidized price, unless you want an iPhone for the sake of having an iPhone the 8820 makes for the more appealing choice.
Rumor also has it RIM was/is ticked off over AT&T's decision. Can you blame them?!
