Keep in mind that Sprint and VM are in the middle of making network upgrades. Your reception may vary drastically while they are working on towers in your area. At my work, I lost all cell signal for 3 weeks and 3g was in and out for 2 weeks. When they finally got it all working again my signal strength jumped by 2 bars, and my 3g speed went from around 350kbs to 1.5mbs. Just give it a little time, they may be working in your area.
