I've had an iPod Touch for a while, and jailbroke it before 1.1.2 ever came out. Would it be worth the risk/hassle to restore the iPod (thus unjailbreaking), upgrade to 1.1.2, and re-jailbreak? I know 1.1.2 had the "Add New Event" thing to iCal but I have that anyway. But are there performance enhancements, bug fixes, etc., that I'm missing out on? Also a side question: restoring the iPod erases the music that's on it, right?
