Though I haven't had a chance to check interactive coverage map, or personal coverage check(retail), you should have descent service. However, it's nearly impossible to tell without actually trying it. That goes for anywhere. Different phones/service will usually react different in any given environment. I coulnd't predict how it may work in side buildings, or in certain topographic/geographic surrondings. Your best bet really is to just try it out. There's a 14 day buyers remorse period, I'd say it can't hurt.

I just upgraded myself to the sidekickII and I must say I LOVE IT! It's worked EXTREMELY well for me! I'm in the southeast region, though...
