Why do I need to stay away iOS4 for now?
I jailbreak my iphone with spirit, and my iphone is 3gs(old bootroom, baseband 5.12.01). How can I unlock it to use w another carrier?

Use Sn0wbreeze that installs custom firmware and installs cydia. With cydia you can install Bootneuter that unlocks your phone.
