I've been having numerous issues with my jailbroken 4S. Data wasn't working at all, notification issues, etc. I restored it today, installed 5.1 fresh from Apple, and then used a backup I made in iTunes prior to wiping it (to get my settings and whatnot back.) One of the issues that remains, even after restoring, is the Facebook and Twitter websites won't load in Safari. Facebook never loads and shows a white screen (it looks like it's trying to load still) and Twitter finishes loading but only shows a blank white screen. What's going on here? The issue must be in my backup, but I don't know what would cause this. Is my only option restoring again and starting fresh? Thanks for the help.
