Thanks ... I do have a call in to our Nextel rep about the phones and also about my Sprint wireless card to see if it will work there also, but he's on vacation right now. I have plenty of time but figured I'd post the question here too. Our rep is pretty good and if he tells me that it will work and no big charges and he's wrong he'll get it taken care of, unlike if I call and talk to some CSR at Nextel.
Dylan, I sent you some more info via pm, hope it helps. If you have any questions let me know!
