Directly from sprint, I they will not be releasing a BB with qchat or any smart phone with qchat. The reason The current phones that are about to be released are to test the water and work all the bugs out of the system, basically a public "beta" test of the new system on some decent phones. What's being released here's the line up Sprint’s QChat Lineup Revealed (Phone Arena). This is what I was told from Sprints BB Support Line.

It makes sense to me, that way if qchat flops a lot of expensive smart phones that would be made end of getting thrown out. I was told to wait about 9-12 months when a BB with qchat should be out.

not too bad. like you said you want to ensure that it works and fix any major issues when rolled out to the wild. if it works then deploy in a big blanket to all
