Not a lot of surprises here, but T-Mobile has just confirmed a pair of earlier rumors surrounding three different Android-based phones from Samsung. That includes the Samsung Exhibit 4G and Gravity Smart, which will both indeed be launching on June 22nd, and the entry-level Samsung Dart (pictured above), which is available today for free on a two-year contract. The Exhibit 4G is the highest-end of the lot, with a 1GHz Snapdragon processor and Android 2.3, while the Gravity Smart drops things down to Android 2.2 but adds a QWERTY keyboard, and the Dart packs some specs that T-Mobile's choosing not to highlight for the most part -- though it's apparently a variation on the Galaxy Mini, which boasts a 600MHz processor and 3.1-inch QVGA display.
