Engadget Mobile has recently put up a pic of the Cingular Blackberry Pearl. The major difference seems to be that the Cingular variant has broken up the all black keypad found on the T-Mobile version, with a streak of grey on down the middle over top the numeric portion of the keyboard.

I probably need to see a much higher resolution picture of the Cingular BlackBerry Pearl to be sure, however, I think that I like the T-Mobile all black version better.
