I too am on the must have 850 list. Unfortunately not all companies provide their individual coverage maps on that site, but the large PDFs http://www.coveragemaps.com/gsmposter_americas.htm and http://www.coveragemaps.com/gsmposter_world.htm look to be a composite of all the GSM providers, some of which add to the 850 range. I'm aiming for T-Mobile, and luckily they have 850 roaming agreements with companies that are in the areas in which I travel.
