..Is up for preorder in the U.S.
U.S. smartphone buyers looking to grab Samsung's Galaxy S4 finally get their shot today.
Preorders for the next Galaxy-class phone have launched at both AT&T and U.S. Cellular today.
The Galaxy S4 is listed on AT&T's Web site with a ship date of April 30. But actually getting to the preorder button is a challenge. Entering a variety of different zip codes in the location field kept triggering a message telling me that "the device you've selected is not available in your area."
Some people seem able to pick up the S4. Tipters told Engadget today that AT&T's site does show the device as available for preorder in certain locations. For those people, the page confirms $199 as the two-year contract price and $639 as the off-contract price. The phone itself is available in either White Frost or Black Mist.
According to GSM arena , S4 is a solid 8 core phone :
CPU Quad-core 1.6 GHz Cortex-A15 & quad-core 1.2 GHz Cortex-A7
with 2 GB RAM with a PowerVR SGX 544MP3 GPU.
