Samsung Electronics announced Wednesday it will launch its Galaxy S smartphone through 110 mobile operators in over 100 countries at the same time.

In the U.S., the Android-powered device will debut with all four of the nation's largest mobile operators -- AT&T, Verizon Wireless, T-Mobile, and Sprint Nextel. It is the first time for the cut-throat competitors to unveil the same product simultaneously. Each mobile operator will offer the same essential product, although the designs will vary a bit, Samsung said.

Other wireless providers to offer the device include Vodafone of the U.K., Orange of France, Germany's Deutsche Telekom, and Japan's NTT Docomo.

Samsung's flagship smartphone is viewed as a rival to the Apple iPhone, which currently dominates the world smartphone market. "The Galaxy S display viewing angles are bordering on perfection," GSMArena, a leading electronics review website, praised. "The sensitivity is as good as is to be expected in a capacitive touchscreeen unit." It is "the new leader of the Android pack."

CNET, a popular U.S. tech news website, called the Galaxy S one of the most-anticipated smartphones of the year.
