You've probably never heard of the Samsung SGH-T999, SCH-I535 or SPH-L710, and that's not surprising, but if you regularly buy the latest and greatest smartphones, one of them may soon be part of your life. All three codenames recently appeared at the Wi-Fi Alliance, where each of the devices has now been certified for dual-band 802.11 a/b/g/n Wi-Fi. That in and of itself wouldn't tell us how important these devices are, but believe it or not, those code numbers actually do: it just so happens that the existing SGH-T989 is T-Mobile's Galaxy S II, and the SCH-I515 and SPH-L700 are variants of the Galaxy Nexus for Verizon and Sprint respectively.

Since we know from experience that Samsung increases the middle of those three digits to indicate a phone's successor and Samsung likes to ship near-identical devices for multiple cellular carriers at the same time, we might even be looking at three variants of the same top-tier smartphone for T-Mobile, Sprint, and possibly Verizon. If we had to guess, we'd say it would be modeled on the Galaxy S II HD LTE, and it just so happens we're already aware of a T-Mobile counterpart, the Galaxy S Blaze 4G. You can almost certainly expect to hear more about the phone at Mobile World Congress in two weeks.
