5 Reasons to Jailbreak iOS 10 & iOS 10.2 and 6 Reasons Not to Jailbreak

This is a Work iPhone or You Have No Backup

Do you use your iPhone for work, or is it one that work provides you? 

If you answer yes to either of those questions you should probably stop and keep your iPhone stock. 

You may not void a warranty, but if you go to your company IT department asking for help with a jailbroken iPhone you may get no help.

It's best to jailbreak if you have at least one backup device that you can switch to in case something goes wrong. It could be a super old iPhone or even just an iPod touch you have laying around.
