Undo a jailbreak

[surfer13]

Hey guys,I jailbroke my phone the other day and I was running into some errors and such so I decided to restore my phone to get rid of the jailbreak. I only had the jailbreak for about 2 days and never backed it up in itunes. When I restored my phone today I choose to restore from back up,and I chose a day in october so It was far from the day I jailbroke it. Now my question is,I should be fine doing this since I never backed up my jailbroken device and even if I did I chose a back up from last month correct? I just dont want any jailbroken material on my device. Thanks for the input.

any backup will be fine. no jailbreak (unofficial) items will transfer over.

once you reinstall official fw you will erase the jb, just make sure to pick a backup from before jb to be on the safe side from something carrying over...
