With the recent rumors circulating about the BlackBerry (Curve) 8910, it doesn't surprise me that the Curve 8900 has taken a graceful bow and left the T-Mobile retail scene. Though it has reached the "end of its life cycle," the 8900 represented one of the first models in RIM's "new design" category and was a great upgrade to the Curve 8300 series. I made some calls this morning and found a few stores with Curve 8900's in stock, so if you're interested in picking one up, I would recommend a store visit as quickly as possible.
For now, customers have the option of picking up the Curve 8520 or the Bold 9700 until the Curve 8910 makes its way onto the scene. How about it - trackpad, OS 5.0, and a revised design of any interest to you?
