iPad 2 4.3.3. JB.
Wanted to start surfing with Safari. Swiped up to change apps, and couldn't find it. Odd since I'd been using it just a little while before. Relaunch. Swipe up, change to another app, swipe up, no Safari icon...
Went into settings, where I know there's a Safari option (between Mail and iPod). And it's gone! No way to open the Safari options. It works fine, I just have to relaunch it from the icon on the Springboard.
I've been installing a number of apps from Cydia, but nothing at the moment the problems started. I had the Safari remove cache SBSettings extension, and removed that but that doesn't do anything either.
I backed up the iPad, restored to a backup 2 days ago (and I would have noticed it not working, so I'm sure it still worked then), and it still doesn't show.
Any ideas? Any ways to re-install Safari?
