Samsung SPH-L520 reaches the FCC, may be a Galaxy S4 Mini for Sprint

We've only seen hints of the Galaxy S4 Mini launching in the US through AT&T and Verizon, but a new FCC approval suggests that Samsung's mid-size smartphone could reach Sprint as well. The filing reveals an SPH-L520 device with both a Sprint-native LTE frequency and a body that's only slightly larger than the regular GS4 Mini. That sounds like a positive ID, although we won't make too many presumptions -- this could be a carrier-specific phone that happens to sport Mini-like dimensions. If the smaller Galaxy does arrive on Sprint, though, we won't be caught off-guard.
