I have a WP7 LG Quantum. Got it when it first came out. Love the OS. Really puts the IOS, Android (IOS Clone) and the lowly BB to shame. There is no WP7 devices offered by Bell. Any news as to if and when any new devices will surface.
SaskTel is supposed to be getting the Nokia 700. I don't know if Bell will be as well, but they usually both get the same line of phones. (SaskTel gets phone from Bell)
