In Australia it is marketed as the Hiptop Slide and in the U.S. as the Sidekick Slide. It was first released on November 5, 2007, through Telstra in Australia. T-Mobile USA release followed two days later, on November 7, 2007. It was later released in the UK and Germany by T-Mobile (as opposed to the Sidekick LX only being released by T-Mobile USA). The Sidekick/Hiptop Slide offers the same features and services as every other Danger device and an update to Danger's latest OS version (4.0). Like the LX, this Sidekick for T-Mobile USA adds the Multimedia Messaging application and provides support for T-Mobile MyFaves plans.
