“A cloud is made of billows upon billows upon billows that look like clouds. As you come closer to a cloud you don't get something smooth, but irregularities at a smaller scale.”
- Benoït B. Mandelbrot
The Danger Hiptop, also re-branded as the T-Mobile Sidekick, is a GPRS/EDGE/UMTS smartphone manufactured by Danger Incorporated (since 2008, a subsidiary of Microsoft).
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.
On October 2, 2009 Microsoft suffered a massive outage which resulted in prolonged unavailability of data for US T-Mobile Sidekick users. T-Mobile suspended the sale of Sidekicks. On November 16, 2009, Sidekick Sales resumed and new activations are working as expected against the back-end services. The majority of existing users had recovered all contact, notes, calendar and photo data by the end of November. Microsoft invested millions of dollars subsequent to the outage on October 2 to ensure better customer experience for all Sidekick users.
