Someone on another forum was trying to tell me that Nextel phones would work without cell towers (i.e. CB radio like). i explained to him that even though you can talk to someone else on another nextel phone they are both still relaying off the tower and won't work if the tower goes down. I'm thinking there maybe a nextel model with some sort of local cpability, maybe on FRS frequencies but even is so they wouldn't be able to transmit very far. Anyone heard anything about these.
