I got a call last night for Berlin Heights. I remembered this morning that I needed to be able to tether when I work over there. I quickly downloaded the VZAccess software (no ICS Boohoo, I love that prog). I was pleasantly surprised that VZAccess worked much smoother than the last time I used it. Connecting was a snap, I did not have to end the data connection or disable Active Sync or re-enable data and push when I disconnected.
Of course it doesn't have EVDO Rev. A which I do miss.
I am sure that Verizon has improved their software, but the ease in which worked was mostly due to the BB I think.
