It's rumoured AT&T are paying for the exclusivity to lock out all the other players from selling the device. Then they can do whatever they please, promote it, set it in the corner with the others and focus on the iPhone and Galaxies as they always do day in and day out.
To me it appears AT&T does not care about the phone, they just want to block everyone else from offering it which is more detrimental to the brand and to Nokia not to mention the customers.
I'm in no hurry, I'll wait till it gets delivered throughout the market. I jumped on the 920 the first month and had issues after a couple months and had it serviced which they replaced it and that one had a few new user experience tweaks to it the original didn't.
Overall, no need to rush, it's coming, just sit back and wait. Email AT&T and Nokia your annoyed feelings too. It may actually help for the next round of new releases.
