TetherMe: Enable Native Tethering on iPhone / iOS 4.0.1 Even If Your Carrier Doesn’t Support It
If your network carrier doesn’t allow you to tether your 3G or EDGE connection from your iPhone to say your notebook, TetherMe is for you. Unlike MyWi which costs around $20 bucks, TetherMe enables native tethering option on all iPhones from iOS 3.x up to iOS 4.0.1.
TetherMe dynamically enables native tethering for iOS 3.x and iOS 4.x+ devices. This should work on any carrier without the need for customized bundles or preferences.
TetherMe also bypasses signature checking and allows you to edit your carrier bundle manually if you so desire. This is required to enable MMS functionality on T-Mobile. TetherMe does not enable the loading of APN configuration from .mobileconfig profiles at this time.
TetherMe works by allowing tethering on any APN that is used for iPhone data. So as a result, your carrier should not charge you anything extra. TetherMe is available in Cydia for jailbrokeniPhones under BigBoss repository for a mere $2. Once you have installed the app, reboot your iPhone and then navigate to Settings –> General –> Network to enable or disable it.
