Alright so I've had the jailbreak for about 24 hours now. No real issues besides the Weather app not opening (which should be fixed soon apparently as the devs say they know why it is happening so we're just waiting on it to be pushed to Cydia as a package update). Other than that, I've had the phone get stuck on the Apple logo and not boot. To fix it, you have to hard reset (home button+power button). If that doesn't work, others have stated that if you do a hard reset WHILE the iPhone is plugged into a computer with iTunes running, it will boot properly (not DFU mode either, just a normal reset while it's plugged in).
