The newer version of the T-Mobile's Sidekick device became available today. It boosts a new 65000 color screen, AOL® Mail functionality and new monthly service options. The color screen swivels up to showcase a full QWERTY keyboard. New and existing T-Mobile Sidekick customers can now sign up on any T-Mobile voice plan and add unlimited email, Web browsing, AIM® and text messaging for $20 a month. Customers who want to use just the device's data functionality can get a stand-alone plan that includes unlimited email, Web browsing, AIM® and text messaging for $29.99 a month, with voice calls billed on a pay as you go basis for just .20 cents a minute, with domestic long distance and roaming included.
