So far, Samsung has two models of the Galaxy S phones, Samsung Vibrant
and Samsung Captivate, available on T-Mobile and AT&T respectively.
But two more Galaxy S devices are expected to debut soon–Samsung Epic
4G on Sprint and Samsung Fascinate on Verizon Wireless.
Samsung says all Galaxy S devices will be upgraded to Android 2.2
Froyo operating system.

Motorola Droid as the best-selling Android phone. Motorola recently
launched Droid 2 on Verizon Wireless.
