Pre-orders of the Samsung Galaxy S 4 have already begun at AT&T, but the operator has been oddly silent about the actual date customers can expect to purchase one in stores and online. Now that T-Mobile and Sprint have both announced specific launch dates (April 24th and 27th, respectively), the largest GSM carrier in the country has followed up by declaring its intent to sell the flagship Samsung device on the 27th of this month. This is four days earlier than the anticipated pre-order shipment date, which means the HTC One has merely a full week to bask in the spotlight by itself. What's more, if you simply couldn't wait and jumped on those pre-orders, you'll get yours a full 48 hours early (read: April 25th). As expected, the GS 4 will be offered for $200 (16GB) and $250 (32GB) in both black and white.
