iOS 8.0+ compatible version of TetherMe
Enables the native tethering functionality of your device and gives you the option to share data from a VPN or to share a WiFi connection to USB. This DOES enable the instant hotspot functionality introduced with handoff in iOS 8.1.
TetherMe also allows you to edit your APN settings. There is no App installed, settings are available under TetherMe in Settings.
This method should work on every carrier without any additional user interaction; however, if you decide to tether without your carrier's knowledge and they find out, we will not assume responsibility for any additional charges or fees incurred.
TetherMe for iOS 8 is a separate package, so users who purchased TetherMe for iOS 7 (and before), will pay a small upgrade fee; however, if you purchased the package in the last 18 months, it will be a free upgrade. TetherMe is available for $4.99 for new users, or $2.99 for those upgrading. The tweak is available in Cydia Store on the BigBoss repo.
