It was just a matter of time before somebody came up with a tethering solution for both the iPhone 3G and 3Gs. Simply follow the steps below.
Here’s an extremely easy way to enable tethering on your iPhone 3G and 3GS (even on AT&T!) by just visiting a site on your iPhone’s Safari. No jailbreaking needed. Here’s where you go:
Then scroll down to the Tethering & Internet Settings, then choosing your country and provider. This works for both AT&T and T-Mobile, and will let you install the appropriate configuration.
Now go to your settings and enable tethering. Check the video walkthrough above to help you configure tethering.
The source claims that they have been testing this for about a day and it’s been working quite well. Just be careful though, that AT&T doesn’t officially sponsor this and might charge you extra for using tethering while you’re not supposed to. Monitor your bill and charges.
If this procedure disables visual voicemail on your phone, just go and reset your network settings, and it should be fixed. If that doesn’t work, try updating your phone with an older version of the AT&T carrier settings.
