“It will have a Platform version of 2.7.0, where we currently have versions 2.3.0 and 2.4.0 for OS versions 4.2.1 and 4.2.2, respectively. … The one deduction that can be made is that OS version 4.2.2 [available only on the BlackBerry Curve and BlackBerry 8830, so far] may very well be the last we’ll see of the OS 4.2.x family, one of the strongest series from RIM to date.”
Jibi goes on to speculate that the OS might come out with the next Pearl, which wouldn’t be entirely surprising. You can bet your thumbs BBCool will be keeping an eye out for any future developments on this front. Cheers, Jibi!
