I know that the last Sprint update (or maybe the one before it) was supposed to have resolved issues with the delayed response you got when trying to dial a number (especially in trying to use quick dial). And it did work for me, but I recently had to change my 650 out for a new one. I used Backup Man to xfer all my data to it. It definitely has the latest Sprint update (as far as I know anyway - 1.12).

On my older 650 (the one I had to swap out), the problem was resolved. But now on this one, I get the same problem, as well as delays when I try other things as well. It's just sluggish to respond in many situations.

Any suggestions? It's really frustrating...
