The HTC Dream, also known as the T-Mobile G1 in the United States, was the first commercially released Android phone. Later on, the Android operating system was purchased by Google and further developed to compete with other major smartphone platforms at the time including BlackBerry OS and iPhone OS (iOS). In April 2009, it was announced that T-Mobile had sold over 1 million G1's in the United States! The Dream was discontinued on July 27, 2010 by T-Mobile and ultimately replaced by the T-Mobile G2, an updated Dream device, in October 2010. This updated device was T-Mobile's first "4G" smartphone.
