Popular tweak TetherMe has received a major update that makes it fully compatible with iOS 7 and 64-bit devices, which includes the iPhone 5s. The latest version of the tweak supports iOS 4 through iOS 7 making it compatible with almost every iOS device out there.
It is an ideal tweak for those who like to use the Personal Hotspot feature on their iPhone. Even though this feature is available on iOS by default TetherMe offers an experience to users that is free of carrier limitations. This means even if your carrier has deactivated the personal hotspot feature for you TetherMe will override the restrictions enabling users to fully take advantage of this functionality.
This tweak does not add any icon on the homescreen and can be activated from Settings > General > Network.
TetherMe tweak is available in Cydia under the BigBoss repository. It would cost you $4.99.
It works for me on the ios 7 JB. I purchased this under ios 5.x and have been using it ever since and never had to re purchase. Not as cool as Mywi but gets the job done and cheaper.
