iPhone 101: How to Tether Your iPhone 4. I just set this up. It really works...

With the release of iOS 4, AT&T finally allowed internet tethering on the iPhone. Because there is no jailbreak for the iPhone 4 yet, we cannot use apps like MyWi to tether your iPhone or even turn it into a wireless hotspot.

So far, if you want to tether your iPhone 4, you're gonna have to play fair and deal with AT&T. Tethering on your iPhone 4 will come at a hefty price of $20/month plus $25/month for the 2 GB DataPro plan by AT&T. That's a complete rip off but that's the only solution to date.

If you're not turned off yet, here is what you have to do to set up internet

tethering on your iPhone 4:

Step 1: Go to Settings > General > Network > Set up internet tethering.

Step 2: A message will show up telling you that you have to call or visit AT&T's website to enable tethering. Either call them or go to your account online to activate the option.

Step 3: Reboot your iPhone.

Step 4: Plug your iPhone in your computer.

Step 5: Go to Settings > General > Network > Internet Tethering > On. Now either choose to tether via USB or Bluetooth.

Step 6: Choose "iPhone" from the list of available networks on your computer.

Step 7: Enjoy the interweb!

As I said above, AT&T prices for this option are outrageous. If you're on a jailbroken iPhone 3G or 3GS you can always tether your iPhone for free using MyWi.

BTW, Sent this while tethered.  Not terrible.
