We've once again been blessed with an OS for an unreleased device. This time around it is the upcoming BlackBerry Pearl 9100 aka Stratus. This is not a service OS, and therefore can be booted up using Desktop Manager. For those who are lucky enough to own one a BlackBerry Stratus you should find this beta OS to be a nice build.
For those who may be unfamiliar with what the Pearl 9100 will be - it is the next generation Pearl (obviously). It will sport a nice trackpad and be sleek and sexy as the Bold 9700 and Storm2. We've already discussed it's exact specs, which you may find as a nice read.
