We hear from MobileCrunch [via] that official iPhone tethering will be coming soon to AT&T. How soon is "soon" we don't know, whether data will be capped or unlimited is a mystery, and exactly what sort of plan will be involved is also up in the air.

It's a safe bet to say that AT&T will not be including tethering in the standard iPhone plan. Tethering costs in the US generally run a minimum of an extra 20 bucks a month, depending on carrier, business, and the phase of the moon. In other words, you may still want to think about jailbreaking and tethering on the sly with PdaNet - just don't tell 'em we told you.

How much would you be willing to pay for laptop tethering?
