There is one spot at work where I get about 1 bar of sprint service, but verizon has full bars. With my old phone, whenever i was at work, there was an option to turn the phone to sprint only, roam only, or automatic. I would turn it to sprint only, yes it used the battery a bit more but i wasn't charged for roaming on phone calls or data. Today, i noticed my evo went into roaming automatically. But when i left work, it stayed on roaming for about a half hour, even though i have great sprint coverage everywhere on my way home. I looked, but could not find an option like my old phone had, so if it ever gets "stuck" in roam mode, i can switch it back.
