SaveMe (used to be screensaver) by maxthebest.

Installation:
-Put the prx to seplugins folder
-Enable it through recovery mode.

Changelogs:
V2.0
-Now the prx runs in kernel mode (so it kicks out most of the freezes problems)
-The prx doesn't crash when launching internet browser (thanks to kernel mode)
-If hold is down, the prx won't launch (usefull on USB connexions)
-Deleted the config file (it will be back soon...) (so time is set to about 30 seconds and cpu to 10MHz) 
-Now the screen is switched off rather than displaying black background (saves more power)
-Nothing is displayed anymore (as the screen is off, it would be useless)
