Amazon has another great holiday smartphone deal for you: The online retailer is dropping the price of Nokia’s N900 to $530 minus another $50 (after mail-in rebate) for a $480 take home price. The N900’s US retail price is $649 without the carrier subsidies making this pretty little smartphone quite the splurge. This unlocked cell phone has not been released yet and is only compatible with GSM carriers like AT&T and T-Mobile, so unfortunately it won’t work with carriers like Verizon Wireless and Sprint. The N900 has super fast 3G capabilities, a 3.5-inch touchscreen display, slide-out full QWERTY keyboard, a powerful Maemo 5 operating system, a 5-megapixel camera/camcorder, a GPS for navigation, Wi-Fi networking, and Bluetooth stereo music.
