So I just purchased a used 4s, and it's jailbroken. How can I unjailbreak it? Is it possible to right off the phone by erasing all content and settings or how can I do it?
Plug it into iTunes and restore it then set it up as new. You can erase all content and settings as well. Does the same thing.
It's not necessary to put it into DFU mode. You can still restore it in iTunes normally.
It won't ruin my phone if I do it from the phone?
It'll need to be connected to iTunes at least once.

No. It's essentially a restore.
What do you mean?

Alright I just want to make sure that nothing with happen to the phone
Alright, would I have to do anything else on the phone other then just clicking restore? Do I have to do what the poster above said to put it into the other mode?I would do an iTunes restore to be safe though.

Nope. Just click Restore then set it up as new afterwards.
Don't do an erase all settings from the phone. It'll turn it into a rebooting-loop phone. Not a huge deal, just need to plug it in, restore as new phone and you'll be fine.
I'm just going to plug it in right from the beginning just to be on the safe side.
It worked, thank you guys for the help
