How can I tether on AT&T?

Only if it is jailbroken, I believe. If you are jb, look up TetherMe or MyWi.


If not jailbroken, your option is to contact AT&T and add a Tethering Plan to your account, at last check I think it is $50/mo for a 5gb plan, month to month. Or change your plan into the Data Shared plan and get Tethering for free but it goes towards your monthly limit of GBs.

 

It's not possible on a non-jailbroken iPhone to tether with an unlimited data plan, UNLESS you managed to snag at least one of the illicit tethering apps that were sold in Apple's appstore before they were pulled. Even in that case, you can only tether a computer to your iPhone--not a tablet.

 

There are some tethering apps out there.

where can we get some?

 

I got FlashArmyKnife before it got pulled from the app store

 

Yes, he could use MyWi but there's a huge possibility that he'd get caught by AT&T. They've been cracking down very hard lately on tethering.

 

I haven't used it myself but here's an option that bypasses the need for an app:

Lucky you, can you tether that to an un-jailbroken iPad?

I considered buying it, but I figured I already had handylight. Then got the iPad and found out I can't tether to an iPad with it unless the iPad was jailbroken.
