From what is being reported on BGR, ATT should get it first with up to a 6month exclusive deal. From what I'm reading today it looks like TMobile may be the first to get the "Kickstart" in September. It looks like everyone is getting in on the BB summer frenzy of '08.
It looks like its going to be a great summer for the BB community!
Be interesting to see since T-Mobile is set to start rolling out their 3g network this summer. It's on a different spectrum so the radio would have to be different. Any specs to show what frequency the radio is on? Could be a big indicator
