AT&T has been dragging its feet on data tethering for months now, so if you're fed up waiting for official support and desperate to tether your iPhone's internet connection, weblog MobileCrunch details how to do it on the latest iPhone OS.

The multi-step process isn't all that difficult, but you'll want to set aside a little bit of time. In the brief overview, enabling tethering works like so:

1. Jailbreak your iPhone with blackra1n (available for Windows and Mac).
2. Unlock your phone with blacksn0w—which you can do through the blackra1n icon on your iPhone post-jailbreak.
3. Install a custom IPCC file via mobile Safari.
4. Turn on tethering in your iPhone settings.

The MobileCrunch post walks through each step in excellent detail, so if you're eager to tackle tethering, it's a great guide for accomplishing that. Keep in mind that jailbreaking isn't all that encouraged by Apple, but if anything were to go wrong, you can simply restore your phone and be just fine. (Trust me, I've done it a lot over the past few years.) Also, we can't make any promises should AT&T decide to get all upset over your tethering, but so far we haven't had any problems.
