NetShare iPhone Tethering App Reappears in App Store [Updated]
The $9.99 application promises to allow you to share your iPhone's network connection with your computer.
Share your iPhone's EDGE or 3G Internet connection with your computer using NetShare. NetShare provides a SOCKS5 proxy for your computer to connect to.The application appeared briefly last night but was pulled for unknown reasons. Note that the tethering application does not appear to work with all traffic (such as mail, AIM requires configuration), but does work for Safari web browsing. The App is available in iTunes: App Store link.
Screenshots of the instructions were posted in our original story and a forum user has written up a detailed tutorial.
Notes: To get Firefox or Camino working, you can follow these instructions. It is reportedly possible to route all network traffic through the iPhone, but may require another application.
Notes 2: Windows XP instructions.
Update: NetShare has again been removed from the App Store without explanation from Apple.
