Upgrading

[sueeKay]

Hey iPhone users.
Here's the go. I am currently still on iOS 7.1 and tethered jailbreak with pangu. I want to upgrade to the latest iOS. How do I do it all over again. I'm so delayed and I need a change.
Any advice? Please recommend me with the best of the best

The latest iOS is 9.1, and currently there's no jailbreak available for this software version. It's also the only version you'll be able to update to, so if you decide to go for it, you'll lose your jailbreak.

Use iTunes (computer) to update your device, and make sure there's a recent backup.
