With the Samsung Galaxy S 4
revealed to the world yesterday in NYC, both AT&T and T-Mobile now have signup pages
. All that is required is for you to submit your E-Mail address and they will notify you when the Galaxy S 4 is available for purchase (or possibly even pre-order). Unfortunately, no further information is listed, such as a price or date; and you may notice that Verizon and Sprint have yet to post a signup page - though with history as a guide, we'd expect them to eventually.
