i had an impulse to uninstall this this hack through Cydia morning to test out the battery life without it. but after uninstall, press the Reboot button, and the phone will not start up. it got stuck in an endless loop of SB trying to start.
in the end, i had to restore to earlier backup, and ended up rushing off to work, with only the basic iPhone apps and no music
this will be my 4th time restore on os3....... it's such a bad release, and they had so many Betas. when i get home, im going to do a final restore, and start from scratch, also no more MMS/push hacks. lets hope the battery life comes back.
