It's been rumored again and again, but AT&T seems to be intent on launching the BlackBerry Curve 8900 and the Pearl Flip 8210 soon.  Our source told me that the Curve 8900 will (barring any further delays) most likely launch in late March/early April, followed by the Pearl Flip 8210 shortly thereafter.  From what Fudzilla claims, their tipster has spotted the SKU for the Curve 8900 in AT&T's POS system.  When these new models launch, AT&T will officially offer three of the four newest BlackBerry devices, and as a result, will begin to discontinue the older models - namely, the 8310.  It should be replaced by the 8320 in all channels. 

Check out the picture below for a glimpse of AT&T's Curve 8900, and notice the white number keys - a departure from the red numbering on T-Mobile's version.
