How much of the network uses 850? I'm thinking about getting a PEBL phone and am having troubles trying to figure out if I'll lose any network availibility with it. Most reviews say it's a quad band phone, but auctions and sites list it as 900/1800/1900. I'm confused when wondering if I'm going to lose some reception in areas where 850 is only availible. Assuming that's how the system works??? 😁
