cell phone reception, Cleveland, Akron/Kent, and Alabama?

[moominmuppet]

My Dad's looking to replace the current family plan we've got, and we've got folks in Cleveland, Akron/Kent, Huntville, and Sylacauga (SE AL). Anyone out there have feedback about companies with particularly good or bad coverage in those areas?

I'm particularly thinking about T-Mobile, based on a previous recommendation...

Also, I'm only into my second episode with the Colin Baker Doctor and Peri, and I totally understand why they're both so very unpopular.
