The first Android phone, the HTC Dream, was released in 2008. T-Mobile launched it as the T-Mobile G1 in the United States on October 20, 2008, making it the first commercially released smartphone to use Google's Linux-based Android operating system.
HTC officially announced the Dream on September 23, 2008. The phone combined a 3.2-inch capacitive touchscreen with a slide-out five-row QWERTY keyboard and a trackball. Its original software was Android 1.0, which included Google services such as Gmail, Maps, Search, Talk, and YouTube, along with the first Android Market.
The Dream was developed during Android's early partnership between Google, HTC, and the Open Handset Alliance. Its physical keyboard reflected the expectations of the time, when hardware keys were still considered more reliable than virtual keyboards. Android 1.5 Cupcake later added an on-screen keyboard.
The phone reached the United Kingdom in November 2008 and other European markets in early 2009. That regional rollout can cause date confusion, but the device's initial commercial release year was 2008—not 2007, 2009, or 2010.
