If you cast your minds back a couple of months, you'll remember how we told you that AT&T had begun clamping down on people using tethering on their iPhones without paying for the upgraded tethering plan. Emails and SMS messages were sent informing customers that if they continued to tether they would be charged for it. At the time we weren't sure how AT&T knew which people were actually tethering, but now we do and more importantly, we know how to get around it.
Internet Tethering is a process which allows you to use your iPhone as a wireless modem to share its Internet connection with a computer via USB cable or Bluetooth interface. The iOS for iPhone has this functionality (wired-only) built into the operating system but it is only enabled on selected carriers. Fortunately, there is an app called “MyWi” for jailbroken iPhones which can enable wireless tethering on any carrier you like with just a touch of a finger!
Let me clear this up straight. No, the phone you see in the screenshot is not a jailbroken iPhone 4, but rather a jailbroken iPhone 3GS, running iOS 4. The iMovie app you see is basically a “broken” port which was being tried to run on non-iPhone 4 devices but had issues in the end.
