Tethering on a iPhone 3GS? How do you connect your Mac to wifi via your iPhone 3GS?

You can only tether the 3Gs by Bluetooth or USB without a jailbreak.

Do what? Jailbreak or tether?

Tether via USB is easiest, just turn on Personal Hotspot on the phone then plug in the sync cable.

To Tether via bluetooth you'll need to pair your phone with your computer first.

Also, if you're on AT&T you have to subscribe to the tethering plan to get that personal hotspot menu.

Correct.
No wifi tethering on the 3GS on stock firmware.
If you're in the US you need to purchase an additional tethering package to do that or jb your iPhone.

Well it used to be simple. Just download PDANet or Easy tether and connect your phone to your computer and viola!

But now Verizon and AT&T are blocking the use of these apps. Not entirely sure if it is legal but safe to say I seriously doubt it. In order to block the use of it on your phone, they would have to search your phone electronically and that calls into question of 4th Amendment rights. They cannot simply search your phone based on the premise that you might be doing something that is cheating them out of revenue. So far, no one has risen to file a class action but I am sure one is inevitable. In the meantime, Verizon has blocked me. Too bad I am not a hacker - I would inflict equal justice for what they have done.
