Yeah, tough luck. I'm still confused as why AT&T and T-mobile has different 3G bands. Rogers and AT&T use WCDMA 1900 MHz bands while T-mobile and what feels like the rest of the world (just kidding, but at least Europe too) uses WCDMA 2100.
Stop me if I'm way out of my league but my question is WHY?
And isn't it possible to just buy the phone from Rogers directly, cash?
