Cingular is taking the BlackBerry Pearl into its fold as of November 21st, says The Boy Genius Report. The release had been scheduled for November 28th. The Cingular phone (renamed the Cingular 8100) should retain all of the abilities of the T-Mobile version, but will now have a Push-to-Talk feature. The base phone has features such Bluetooth, a 1.3-megapixel camera, and the signature trackball, which Research in Motion promotes as superior for navigating e-mail versus the previous scroll wheel. Video and MP3 files can be stored on microSD cards. No pricing information has been released, though it should compare closely to the $200 contract price associated with T-Mobile.
