This morning AT&T added a third BlackBerry Pearl to its lineup, the GPS-enabled Pearl 8110. Previously, AT&T offered the BlackBerry Pearl 8100, which is now available only as a refurbished device for $79.99, and the Wi-Fi–enabled 8120 ($199).

The new 8110 is priced at $149, $50 cheaper than the 8120 and with many of the same features, including a 2-MP camera, 3.5mm headphone jack for listening to music, and a side-loading microSD slot for adding music and video to your BlackBerry. It also has the same SureType keyboard.

Oh, and it comes with an “exclusive Indiana Jones ringtone.” If you thought BlackBerrys were still just for business, there’s your proof that it’s not. On the business side of things, though, AT&T is hoping that the Pearl strikes interest in potential AT&T BusinessTalk subscribers, a service that lets small businesses talk to multiple phones on the same contract for free.

The 8110 supports the AT&T Navigator software for GPS navigation, as well as YellowPages.com for local search, and both applications are preloaded on the device at the time of purchase.

The 8110 is the exact same size as the 8120 and has the same talk and standby times, with 4 hours of talk time and 15 days of standby.

Fans of AT&T’s outgoing red 8100 Pearl will be pleased to know that the 8110 is available in both red and titanium. The 8120 was only available in blue.

When it comes down to selecting your new BlackBerry Pearl with AT&T, ask yourself the following questions: Do you want GPS and local search, or would you prefer Wi-Fi? And is the Wi-Fi worth $50? The choice is yours.
