AT&T's Galaxy S 4 page lists April 30th ship date, $199 / $639 price for 16GB

We saw AT&T open up a registration
page for the Galaxy S 4 almost as soon
as Samsung's presentation was over, but
now that link is exposing a bit more
information. Several tipsters let us
know that for customers in certain
areas, the website is now showing the
16GB GS 4 available for pre-order in
White Frost or Black Mist. Some of the
details are visible to all, including that
the phone is promised to ship April 30th
and has an off-contract price tag of $639
($199 w/ two-year agreement). Those
who can get further in the ordering
process report it's expected to arrive at
their homes on or before May 3rd, with
two-day shipping. Hit the link below if
you're moved to get your pre-order for
Samsung's latest standard-bearer in as
soon as possible.
