This does explain why T-Mobile skipped on the 7130xx.
T-Mo internal reps have got to be laughing their heads off.
This is how it's going to look in October:
Cingular: grey 8700c and 7130c
T-Mobile: all black 8700 and 8100, plus the 7100's of yesteryear going like hotcakes.
I'll give it to T-Mo, they're "bringing sexy back."
