I found the solution to ALL iOS 5.x devices, go to Settings > Safari > and disable "Private Browsing" Note that Safari will go back to iOS 4.x blue, and more importantly, will fix the cookie and history issues we've been expierencing!!! I recomend backing up with iTunes or preferably iCloud, so when you need to Restore, or Update, you'll get your settings back. Apparently, Apple decided to enable Private Browsing, which doesn't store cookies or history. Mods, could you pin this thread, to save all the "Safari Dosen't work!!!!" threads?
