T-Mobile released the HTC Touch Pro2 and HTC Dash 3G with Windows Mobile 6.1 earlier this year, but these smartphones will reportedly get upgrades to a newer version of Microsoft's operating system in the near future.

Nothing said about Sprint or Verizon but news like this should push them in the right direction.
