Cell phone wifi

I've never seen any phone that was capable of being configured as a wifi hotspot (and that's what it would need to do, some can, some can't) that DIDN'T use that feature to share the phone's cellular connection. But what I think you’re looking for is a way to use the phone as a wireless repeater, so that you’re sort of "bounced" off the phone and back over to the wireless router. Assuming I’ve got the picture right, I doubt it's possible. It’s certainly nothing I’ve ever seen before. It doesn’t even make much sense from the provider’s perspective. They couldn't care less if you had such a feature. If anything, they WANT you to use the cellular network, as much as possible!
