The HTC Dream (also marketed as T-Mobile G1 in Europe and the US) is an Internet-enabled smartphone with an operating system designed by Google and hardware designed by HTC. It was the first phone to the market that uses the Android mobile device platform. The phone is part of an open standards effort of the Open Handset Alliance.

It was released in the US on October 22, 2008, in the UK on October 30, 2008, and has begun being available in other European countries including Austria, Netherlands, France and the Czech Republic in early 2009. It was released in Germany in February 2009 with a QWERTZ

In the US, it is priced starting at $179.99 for new and existing T-Mobile customers if purchased with a two-year T-Mobile voice and data plan, and $399 without a contract. Contrary to claims made by T-Mobile representatives, the handset does not need the data plan to work, however, the Access Point Name (APN) settings need to be changed to make the Multimedia Messaging Service (MMS-Picture Messages) work. The Dream comes in black, bronze (not in the UK), or white.

On 23 April 2009, T-Mobile USA announced it had sold one million G1s since the device's launch.

On 5 February 2009, the phone was released through Optus in Australia, as the HTC Dream. On 21 February 2009, Singapore became the first country in Asia to introduce the phone. It was sold by SingTel between $25 – $159 under various contracts.

Hardware

• Display: 3.2 in (8.1 cm) TFT-LCD flat glass touch-sensitive HVGA screen with 480 X 320 pixel resolution. The capacitive touchscreen makes it unnecessary to use a stylus. The display switches from portrait to landscape mode when the keyboard is opened. Users can interact to bring up or move content with a finger touch, tapping or touch-drag motion. The touchscreen hardware is capable of multitouch gestures , but Android does not currently support it.

• CPU: The MSM7201A is an ARM-based, dual-core CPU/GPU from Qualcomm and contains many built in features including 3G and a GPU capable of up to 4 million triangles/sec. It has hardware acceleration for Java, but this does not accelerate execution of Android applications, as they are targeted to the Dalvik VM, not the Java VM.

• Keyboard: The HTC Dream has a sliding full 5 row QWERTY keyboard. It also comes with a set of 6 navigation buttons:
• phone (green, black in UK) – make outbound calls, receive incoming calls, or open the dialer.
