While T-Mobile is no longer the exclusive US carrier of the Nexus One and while devices still can’t be purchased in stores, T-Mobile is ready to help accessorize your purchase.  Rumors have swirled since the beginning of the Nexus One news that T-Mobile would eventually carry the device in their stores.  Although those rumors persist, T-Mobile is going to start carrying accessories so you can at least protect your investment.  Nothing says you love your Nexus One like a shiny plastic case so keep an eye on your local T-Mobile store to carry these soon.
