I tried the new Sprint 6700 phone. It lacks a screen lock but had lots of features. The Sprint coverage was not as good as Verizon

It also did not pair well with the BMW Bluetooth system. The main problem was that the link would drop in the middle of the call.

My wife has a E815 from Verizon it works perfect in the BMW and has great service coverage.

The draw back to the E815 is that it use only the Vezion system and covergage in upstate NY is limited. The older phone 715? might be a better for remote areas.

I still am waiting for the new Treo 700, which I hope will pair with the BMW.
Does anyone know if the Treo will pair with the BMW?
