Samsung's Galaxy Mega 6.3 still doesn't have an exact launch date, but it has made its way to the FCC. While the Mega was announced with LTE and HSPA+ radios, it appears that this version, model I9200, only has the latter onboard (I9205 is the LTE-equipped variant). It's a safe bet that this particular model won't officially make it stateside, but the reports seem to indicate that it'll play nice with AT&T's HSPA+ bands.
