Just a week back, Google finally admitted that its rumored smartphone was real, and now, the news is that it will start its sale from the beginning of next month. However, the first sales of the device will be by invitation only.

Although as we heard before, Google will be selling unlocked versions of its new phone, but as expected, it will also be partnering with T-Mobile for 3G service.

Apparently, the phone has been named Nexus One, although we would have preferred Googlephone instead. But Google has filed an application with the US Patent and Trademark office on December 10 to use the name Nexus One for its “Mobile phones.”

Some of the key features of the Nexus One include:

• Removable battery
• 5-megapixel camera
• Micro SD Card support
• 3.7-inch WVGA AMOLED display
• Bluetooth 2.1

Apple’s iPhone has overshadowed all of the smartphones this year, but which phone rules in the next year will remain a mystery till the Googlephone, Oops! The Nexus One comes out!
