Better known as the Sidekick in the U.S., the Hiptop from Danger could easily be considered the first modern smart phone. Released in 2002 by T-Mobile, the Sidekick featured a 2.6-in. screen, a full QWERTY keyboard, AOL Instant Messenger, two-way pager functionality, e-mail with attachment support and a full HTML Web browser. Microsoft acquired Danger in 2008, and this past July, T-Mobile discontinued sales of the Sidekick. From 2002 to 2010, a total of eight different Sidekick models were released.
