The jailbreak was successful, but whenever I install anything from Cydia that requires reloading the SpringBoard (Tricker 3G, SBSettings), I'm left on the install log page with an endless spinner. All buttons are unresponsive. Home+Power do nothing. The only way I've been able to getting a working phone again is restore from iTunes.
