How...I currently have a 2wire from AT&T...which router should I buy?are there instructions/links to show or tutor on setup?
Some routers have the option to bridge wireless networks or extend wireless networks, so if you were to create a wireless tether point on your phone and then point your router to always bridge or extend that network, you could wirelessly tether your phone to your router and then connect any other devices to it. just a thought.
A very quick google of bridge a router to a smartphone gave me something very very close to what your looking at doing,

also almost any d-link or netgear or linksys routers have the ability, no all but quite a few of them, and you will not be able to do it from your att router, they almost always block that kind of stuff out, plus if you have 2wire or att service, why are you trying to bridge to your cell phone???
