FUD Zilla reports a cloaked tethering utility for the iPhone managed to get listed in Apple's App Store. However, due to all media attention the app is getting it will likely not be available for long.
Normally it would be censored as soon as its intention was discovered, but Handy Light managed to trick its way past Apple’s App Store reviewers. To enable tethering, you need to configure an ad-hoc wireless network on your Mac, connect the iPhone to it, tweak some network and proxy settings, launch the app, and then literally tap a coded sequence of flashlight colours.
You can't discover the hack by exploring; you need to read detailed step-by-step instructions to get it to work and these have been posted on the world wide wibble. The application is like the $10 NetShare app—which was axed by Apple nearly two years ago. The reason Apple don't like it is that it shares Internet connection without AT&T getting a cent.
