I have Verizon and have had good luck untill recently when I got a new phone. I loose almost every call now. Hopefully I'll get around to replcacing the peice of junk I have now soon. As for nextel I HATE them. The reason for the HATE I have for them are the constant (I mean literaly every day) marketing calls I get from them. Not only are the calls annoying, the callers sound like they have a fifth grade education at best.
