Case closed m’kay? While this isn’t entirely shocking considering we’ve already received documentation showing that T-Mobile indeed moved up the release date to July 15th, it never hurts to confirm again. That’s exactly what Ari Robbins of Phonedog did, asked @T-Mobile_USA twitter the Samsung Vibrant release date and I suppose shockingly so, they replied in the affirmative to the 15th. So there you have it, straight from Magenta’s mouth, case closed.
