Samsung did say it’s ready to supply all US carriers with 4G phones , not just Verizon , and we may already be looking at one of those devices before us. Billed as a T-Mobile exclusive, the Vibrant 4G looks to be a gentle refresh of the current Vibrant handset, with the notable upgrades being the inclusion of 21Mbps-capable HSPA+ connectivity — to speed your mobile broadband up into T-Mobile’s definition of 4G speeds — and a front-facing camera paired to Qik video chat software. The onboard version of Android is 2.2 and internal specs seem to generally match the earlier-released namesake. Speaking of the original Vibrant, these leaked docs also show it’s sold over one million units in its time in the US and is the nation’s best-selling Galaxy S variant. Great, now can someone please leak it to Samsung that Android 2.3 is already out?
