I’m not 100% sure when it dropped to channel, but it looks like T-Mobile has started carrying the Nokia 6600, the Series 60 tri-band phone. Feature-wise, it’s similar to many other Series 60 devices, albeit with a nicer 65,536-color screen than some of the earlier models (such as the popular Nokia 3650). T-Mobile’s site has it listed for $399.99. [Thanks, Naoya!]
