Research in Motion will launch three of its latest BlackBerry smartphones in November on AT&T, the company announced today.

Research in Motion has had a tough year, with declining market share, a massive worldwide outage that angered customers, and a tablet that looks more outdated by the day. While it’s trying to stave off its doom and any further degradation of its brand, the least RIM can do is release some new phones.

AT&T will launch two of the new BlackBerrys on Nov. 6. The first two devices are the BlackBerry Bold 9900, which will cost $200 with a two-year contract, and the touch-screen BlackBerry Torch (pictured), which will cost $100 with a two-year contract. Both the Bold 9900 and Torch 9860 feature HSPA+ 4G for faster data speeds, a 1.2-GHz processor and the BlackBerry 7 operating system, which is marginally better than the previous OS.

The last device of the AT&T trio, the BlackBerry Curve 9360, launches Nov. 20 and will most likely be the best-seller of the bunch because of its $30 price tag. The Curve 9360 features the classic (and outdated) Curve design and a 5-megapixel camera.

It’s unlikely any of these models will attract attention away from the Apple and Samsung AT&T devices this holiday season. Both the iPhone 4S and Galaxy S II Skyrocket appear to be better bets for discerning customers who care about long-term viability and software updates.
