22 carriers supporting at launch. - Anthony Ha

Awesome! - Ross Miller

Including Windows PCs, which is nice - Ian Betteridge

Notice they didn't say anything about AT&T being one of those 22... - Christopher A. Wichura

I'm guessing AT&T will require an additional $10-20 a month for tethering access. - Kevin Fox

Presumably this will be an extra-cost option for the carrier. - DGentry

ohh yeah, AT&T is going to turn the tethering into a premium service thing for sure. - Manuel Arroyo
