Finaly updated to version 4.0, i hope you'll like it (and that not too many bugs was added) :
4.0 :
Complete code and ui rewrite
Better profile management
Added SQL database for profiles management
No "init.d" support needed for "set as boot" option anymore
Removed profile change on screen on/off, android kernel handle that correctly, and this was wasting memory as a service (source: stackoverflow.com)
Removed old "FakeShmoo" kernel support (with obsolete devices name)
Removed "Cpu Stress Test" since it was not accurate for daily usage, better use specific applications
Allow screen orientation changes
Added support for stock tegra 2 kernel (without oc/uv)
Probably more and waiting for reports ...
BE SURE TO RESET YOUR DEVICE CPU SPEED CONFIGURATION (UNINSTALL PIMP MY CPU AND REBOOT) BEFORE UPGRADING TO 4.0
TO GET CORRECT DEFAULT VALUES (ELSE DEFAULT VALUES WILL BE YOUR LAST OC VALUES).
