I need a good phone for work. Im in construction and have busted 2 Blackberrys now and don't plan on breaking my new one. I plan to buy a constuction phone like the Motorola i580 that will take a beating. However, I live well outside of a Nextel/Sprint coverage area. I'm hoping I can buy the phone from them and use it with Verizon or ATT. Is this possible? I do live in their roaming area. Will being on roam full time cost me more like the old days?
