optimus

The LG Optimus One is an entry-level series of touch-screen smartphones manufactured by LG Electronics, Inc. It was released running the Android 2.2 Froyo, and later LG released software to upgrade it to Android 2.3 Gingerbread. Although the basic physical form factor of each variant is the same, the variants have differences in hard button shape and layout, the form of the metal side bezel and the user interfaces added by LG or various carriers. Versions of the Optimus One exist that operate on various frequency bands and either GSM or CDMA-based network protocols. They may also feature one or more variations in hardware, such as a faster processor, the addition of a physical keyboard, a modem with higher theoretical speeds, or a better digital camera.
Since sales first began in mid-November 2010, LG has released ten variants, though some differ very little from others. The Optimus One line is the first LG smartphone line to sell more than 1 million units. As of December 10, 2010 more than 2 million units have been sold worldwide, with 1.3 million units sold in North America, 450,000 units sold in South Korea, 200,000 units sold in Europe and 50,000 units sold in Asia and the CIS.
