What is the best GSM network in the USA to sign up for using an unlocked Nexus One? T-mobile has lower rates if you DON'T get a contract, but perhaps somebody knows of a provider with even more attractive rates?
If you are wanting a single person plan Simple Mobile is a MVNO using T-Mobile's network. Unlimited texts/minutes/data for $60. I think prepaid cards are available via eBay that makes it even cheaper.
