With April slipping further and further away, it comes to our attention that the Galaxy S 4 is rapidly approaching. That is, at least on AT&T, where the GS4 will be available in White Frost or Black Mist colors. More importantly, it will ship by April 30th and has an off-contract price tag of $639 ($199 w/ two-year agreement) for the 16GB model. Add two-day shipping and you’d see your GS4 no later than May 3rd. Sounds good.
