I have never owned a BB but i have used them beacause my brother owns one from work I have right now a PPC-6700. after talking to him I am convinced that I do not need a phone that has to be "soft-reset" every day.

My question (asking for an advice) should I get the Sprint 7250 (EV-DO) or wait for the Sprint BB 8702 when (if) it comes out this year?

I honestly would wait on the 8702.

I have Sprint's 7130e and I like it alot and used to own a 6230. Much better for me since i'm using for phone also. Suretype works great.

The audio quality on the 7250 isnt great. Id either try the 7130e now or wait until the 8702 is released.
