Samsung Galaxy S 4 hits the FCC in MetroPCS and Sprint forms

Get ready for a small deluge of Galaxy S 4 filings at the FCC in the near future. Just a couple of weeks after Samsung's flagship hit the US agency in its international guise, we're now seeing the first US editions of the smartphone receive approval, starting with both MetroPCS (SCH-R970) and Sprint (SPH-L720) examples. Either has CDMA, EV-DO and LTE, although there's variances you'll want to watch for if you're free to choose between carriers: the Sprint version has HSPA 3G for world roaming, while the MetroPCS model drops HSPA but has a broad four bands of LTE meant mostly to support other mid-size American networks, like US Cellular. We still have AT&T, T-Mobile and Verizon to go among the bigger US providers supporting the GS4, although it's just a matter of time before their models make FCC appearances.
