Based on the ATT prices I'm wondering why anyone would choose to teather with their iphone... Yea saving $5 but still... If you teather you're paying $25 + $20 for iphone data and only have 2 gig a month to share among the two devices. If you don't you're paying $25 iphone + $25 ipad but you have 2 gigs on each device. I don't know what ATT is thinking. Yea if you have other wifi devices that might be the only reason but you're still limited to 2 gig a month so thats lame.
