With all the hype around Cingular and its release of the BlackBerry Pearl, we thought it would be only fair to throw more fuel on the fire. According to BlackBerry Forums member walds11 is that T-Mobile has an exclusivity agreement with RIM that is going to expire December 1, 2006. Yes, that's right that date is less than three weeks from today. We really don't think that Cingular will fumble up the oppurtunity to have this device launch on the "Nation's Largest Network" before Christmas. Then again, we think the same of the Treo 750 as well.
