The customizable exterior of the T-Mobile Sidekick iD provides quick modification of the look and feel of the device with easily removable and replaceable exterior panels to show off school pride or match one's style, mood or that day's outfit. Built into the device are the rich communications capabilities that make it simple to be directly connected with friends and family, stay on top of social networks, or act as a study break during dead week.

The T-Mobile Sidekick iD is designed for communication virtually anywhere, with voice calling and a robust variety of options for messaging that provides the flexibility to stay connected. The signature swivel screen flips to reveal the full QWERTY keyboard providing the luxury of always-connected access to e-mail, instant messaging (AIM(R), Yahoo!(R) and Windows Live Messenger), and text messaging.(2)

The T-Mobile Sidekick iD will have T-Mobile's myFaves(SM) available out of the box. The unique myFaves experience provides additional customization with the ability to personalize the homescreen with images of the five people that matter most -- each of which can be changed once a month to keep up with roommates, new college friends or a BFF from high school. The myFaves interface also enables straightforward communications for effortless calling, texting, multimedia messaging and e-mail. Customers can choose from a range of myFaves plans to get unlimited calling to those five designated people -- to any number in the U.S., even land lines (excluding toll-free and 900 numbers) -- that make up their personal network.(3)
