soo everything works and all but on 3.0 theres a long boot if you click reboot in sbsettings and then the screen will go black after the pineapple(apple) disappears...

soo whats up with that? its kinda scary

Uninstall SB Settings / SB Toggles / OpenSSH

The screen going black after the pineapple is normal. The long boot is likely because the iPhone decides to check the filesystem during startup. I have noticed this does not happen if I shutdown properly (hold power/sleep button and slide to shutdown) but if I restart by holding power and home buttons it takes ages to restart.

It is probably the way that SBSettings does the restart that triggers the filesystem check.
