This is not the most newsworthy leak but it does point to something interesting. We heard before that OS 5.0.1 would be the start of Widget support and it looks like that will be the next wave of device OSs.
The team at BBnews.pl managed to get a screenshot of OS 188.8.131.52 installing using their Command Line Auto Programmer which bypasses Desktop Manager. I really wish RIM would release that to the public since it gets annoying to sometimes play with Desktop Manager until it starts installing. It would be even cooler if the tool could be used with any OS.
