The AT&T version costs 0 (the same as the unlocked phone) and it comes in any color you want, so long as you want "awesome black." The carrier is offering a $5-a-month for 30 months promotion if you start a new line or upgrade an existing one, which brings the total price down to just $150. That's a pretty sweet deal, so long as you're fairly sure you want to keep the same phone for two and a half years. This promotion ends on June 3rd.
