If Personal Hotspot feature is not enabled and still missing on your iPhone 4 after upgrading to iOS 4.3 then read this tutorial for possible fixes. However, in case your provider does not allow tethering at all then there is no immediate fix.
We previously shared a tutorial for Windows users on how to Jailbreak iOS 4.3 Final using Sn0wBreeze. This time we got instructions on how to perform the same tethered jailbreak using PwnageTool on your Mac.
iOS 4.3 is now live for iPhone, iPad, iPod Touch and Apple TV. Two best new features are Personal Hotspot and iTunes Home sharing. Jailbreakers and unlockers should hold off from updating at the moment. Free upgrade for all owners of iOS devices.
