The first generally-available wireless device using Hiptop technology from Danger, Inc. Of Palo Alto. Introduced by T-Mobile in the USA in October, 2002. The Sidekick seems to work as a mobile phone, web browser, e-mail client (SMTP and POP), SMS message client, calendar, task list, AOL Instant Messenger client, phone/address/contact directory, and handheld video game. In reality, most of the device's functions pertain to user interface; the processing is largely done on the server side of the wireless connection.
