I use this phone on my T-Mobile account. I pay $9.99/mo to get email on a BB (I use the OWA option and get essentially the same thing as BES without the calendaring). Aso I get internet through the T-Zones icon (which is usually $24.99) ... the limitation is that applications cannot use the internet, just mobile web works. Anyway, the speed of the phone is great... and there are many improvements over my old BB 7105T. The phone looks slick and the display has indredible color. I really cannot find anything to complain about with this phone. At the Overstock price, this thing was a deal!!
