After releases on T-Mobile, Verizon, and Sprint several weeks ago, AT&T is adding its own branded version of RIM's BlackBerry Bold 9900 this Sunday, November 6th for $199.99 on contract. Launching the same day will be the Torch 9860 — the Bold's full-touch cousin, also running BlackBerry 7 atop the same 1.2GHz processor — for a hundred less at $99.99. Moving downmarket, the Curve 9360 will be launching on November 20th for $29.99 on contract (business and government customers will have access a few days early on the 14th). With BBX in the pipeline, the lifespans of these models may be relatively short — but for the 9900, at least, there's little doubt that it'll find an audience.
