Did you back up your phone? If you didn't that might be why.

Yes. I Did Back Up My Phone

I'm assuming you tried restating your phone already, so go ahead and restore your phone with iTunes, then jailbreak it first, once it finishes restore it from back up and you should get everything back. Before you do it make sure your phone was backed up already. You ca do that by going into preferences > devices > backup in iTunes.
