To many of you, this leaked OS will not be of any use. This is service OS for the unreleased BlackBerry Harpoon 8910 (Atlas). If you’re unfamiliar with the Atlas, it said to be an upgraded Curve model for the European and East Asian market.

This is a service OS and therefore does not use desktop manager to install. The OS is compiled into one .exe file – starting it you actually cause
autoastart of cfp.exe, which starts installation. So, it’s more like you
were trying to upload SFI after debranding or unlocking. What’s interesting about this OS is it is the first 5.0.1.xx we have seen. If you are one of the lucky people out there to own a BlackBerry Atlas you should fire this OS up and see what goodies its packin’.

– This is an unofficial RIM software release. If you choose to
do so at your own risk! BB Leaks is not responsible for any
