First RIM releases the model to a carrier. Then the carrier has to test it, add their own branding to the OS (usually with service books), and then the carrier will announce it's availability. Everybody is expecting the 9930 some time in Q3, but that's all guess work and speculation right now.
Knowing my beloved Sprint, they'll get it in November if everyone else has it by August/September. I really want to take a look at the all-touch Monaco, but the Bold Touch 9930 has been exciting me for some time now.
