Samsung will be releasing developer editions of the Galaxy S 4 for AT&T and Verizon, according to the company's site. At least for now, the phone will only be offered in Black Mist, and internal storage is listed as 16GB. It's not clear exactly when the devices will come to their respective carriers, but they likely won't be offered with a subsidy when they do. For those considering purchasing Sammy's latest flagship handset, this offers an alternative to the several variants across service providers, not to mention the stock Jelly Bean version announced at Google I/O.
