well i sell cellphones occasionally at best buy and the problem with the VG 6000 is a cool phone, but i can't use it because it is a digital only phone, i travel to fairbanks occasionaly and the majority of the trip is in an analog only area, SO, i can't use that phone on my drives, which is why i use Cellular One's
GSM phones, which work most of the way up, there is more dead zone than with an analog only phone, but the benefits outweigh the downsides, because the dead zones are more common but smaller than it would be with the 6000
