Yes. Since they got ready of the dual flash and video/hardware accelerator in VZW phone. I did not notice that until i installed MS 3.5.1 and the 3D carousel wasn't so 3D anymore (more like 2D). MS 3.5.1 still looks great on O2 though. The Tahoma fonts looked like crap so I changed it to a font from Nokia that I got from XDA. Looks much, much better.
Battery life seems good.
FYI: I notice that screen lock on the O2 has a player for controlling FM radio and music when the phone is locked. Now that's nice.
Is it better that the Omnia 1, yes. But does not live up to what I expected. I guess thougth that the GSM version would be just what the doctor ordered. I should move to Canada and used the Bell verzion
.
my 2 cents
