I do have a dual model Nokia phone for Sprint PCS, but as you said Sleepwalker, they haven't implemented a plan where you can use both analog and digital services within a service plan. It's great I can roam onto just about any analog service with my phone, but the costs quickly become prohibitive (in many cases exceeding $1 per minute!) Meanwhile my collegues with other cellular providers (I think AT&T as one) just use their phone anyplace and the minutes from their plans apply regardless of whether it's analog or digital service.
To Sprint's benefit, they have been a respectable effort towards covering many of the suburban and even some slight rural areas of Ohio, but it's not enough. Plus digital service in a building just stinks or doesn't work at all. Sometimes I swear I want to go back to analog where I never ever had all the problems!
I'd be willing to give Verizon a try (can't be any worse than what I've had/not had), but then what on earth do I do with my $200 Nokia phone, car adapter, and desktop charging base? I sort of hate throwing away nearly $300 like that!
