I have a jailbroken iphone and I bit the bullet and upgraded from xp to windows 7 so internet tethering works. But now itunnel does not work. Is there a way to get itunnel (either 2.7 or 3.0) to work with windows 7? I can't seem to find a way to do so. I have an iphone 3gs running 3.1.2.
Try this:
1. Go to Cydia and look for Repositories category
2. Select and install iFoneGuide.nl
3. After Cydia restarts, go to the Search tab and search for Tethering Patch
4. Select and install the patch that fits your phone (3G or 3GS).
5. Once that is done, quit Cydia and enter Safari
6. Type in the address bar:

7. Scroll down and select Mobile Configuration
8. Select which ever country you reside in and later the carrier profile that matches you (AT&T, O2, Orange, etc)
9. After that, all you need is to go to Settings => General => Reset and select "Network Settings".
10. Your iPhone will reboot and you should now see Tethering up and working in Network Settings, enjoy!
Uses the native tethering function and is Safer, much safer.
