The Danger Hiptop, also re-branded as the T-Mobile Sidekick, is a GPRS/EDGE/UMTS smartphone manufactured by Microsoft subsidiary Danger Incorporated. The Hiptop is sold by T-Mobile in the United States, United Kingdom, Germany and Austria. SunCom used to sell the device in some parts of the United States, and Fido was the exclusive Hiptop carrier in Canada until sales were discontinued after Fido was bought by Rogers Communications, at the end of the Hiptop 2's life. The discontinuation was mainly because the Hiptop is a competitor to Rogers' BlackBerry business. In Germany, the Hiptop service is also offered by E-Plus including a flat rate tariff. In Australia, the Hiptop device and service were sold by Telstra, until 1 October 2009. The Hiptop was also sold in Singapore by Starhub in 2004, but is no longer available.
