HTC Diamond/ Sprint or Verizon

[Youmoussa]

As I'm new in the US, I need an US mobile and I would like the HTC Diamond. It seems that it will come to Sprint and Verizon in the next month, but in a different model.

The Sprint version is almost like the european one (except for the better battery/bigger size). The Verizon version is supposed to have a SDCard expansion slot but no motion sensor.

I think I prefer the Sprint version, but I've read that there are huge differences between mobile carrier in the US (absolutely not the case in France). I live in San Francisco and would like to access to internet with my phone.

So I need some help to decide.
