iOS 10 Jailbreak Still MIA
If you move to the iOS 10 update you won't be able to jailbreak your iPhone 5.
The only way to jailbreak an iPhone 5 is if you're on an older version of iOS 9. That is, until developers release their first iOS 10 jailbreak.
An iOS 10 jailbreak is in development but we simply don't know when it will arrive for the public. It could be tomorrow, it could be next week, it could be three months from now.
It's extremely unpredictable so you'll need to keep an eye out for news as we push deeper and deeper into the year.
For now, if you're jailbroken or want to jailbreak. you'll want to avoid iOS 10 and iOS 10.1.1.
