EXCLUSIVE: AT&T neuters the BlackBerry 8820 in favor of the iPhone | BlackBerry Cool

According to the linked article, AT&T will cripple GPS on the 8820, just like Verizon did on the 8830.

Can anybody confirm?
If true, will unlocking and using on T-Mobile re-enable fully functional GPS?
Any other thoughts?

P.S. I'm posting this in rumours because I don't know how solid this info is, but if confirmed, feel free to move this thread to the 8800 forum.
