When developping on the iphone (compiling or using a configure script), iit can be boring to sign executable's each times or edit the configuration file line by line ... so here is the way to temporary remove this :

sysctl -w security.mac.proc_enforce=0 security.mac.vnode_enforce=0

to enable it back : 

reboot or : sysctl -w security.mac.proc_enforce=1 security.mac.vnode_enforce=1

Version 2.2 released, it's a bug-fix version, thanks for all the bug reports i received. Some users psp will freez when trying to use the music capability, you should apply the Dark Alex 3.71 fatmsmod.prx patch it should solve the problem ...
