While the Storm, Tour, Pearl, Bold, and Curve 8300 series have either seen enhancements to their product line or are in the process of receiving them, the BlackBerry Curve 8900 is one of the few RIM family members that has been relatively quiet over the past few months.
Days ago, UnwiredView reported that a "Curve 8910" had received Bluetooth SIG certification (see picture above), though no pictures were available at the time. Shortly thereafter, a picture emerged (see below). When it comes to detecting fake pictures, I'm no expert, but it looks like it has everything that would be expected out of an updated Curve 8900 - RIM's new trackpad, a revised keyboard, new call icons, and OS 5.0.
More information to come as we get it.
