Hello. I have a GSM iphone 4 and I have previosuly been JB on 4.2.1. I just followed the iclarified instructions using redsnow to JB on 4.3.1. Now, I am stuck in Safe Mode. I've tried rebooting many times to no avail. I am also getting the 404 errors in Cydia for 4 different repos. Any thoughts about how I can get out of safe mode?
