I'm currently on VW with a GN but thinking about switching to GSM version and getting Straight Talk (ST) like several folks on this forum have suggested. On the ST site there are 2 maps. The one labled "Non-Android Coverage" is great, but when I look at the ST Android coverage map, it doesn't give me a lot of comfort. Why would there be a difference based on phones? Isn't GSM just GSM? Anyone using ST - how is the coverage outside of the few major metro areas shown on the map. Thanks.
