Millions of schoolchildren may be getting ready for three months of lazy summer days, but T-Mob's just starting to get its hustle on. Samsung's Gingerbread-equipped Exhibit 4G and Froyo-laden Gravity Smart have been officially confirmed for sometime in the month of June, but all is quiet about the exact date. If this leaked screenshot above comes to fruition, though, it means we'll be seeing these two phones hit the shelves on June 22. The Exhibit 4G will tempt us with access to T-Mobile's 21 Mbps HSPA+ network, while the Gravity Smart looks to be a splendid entry-level QWERTY slider. The pricing for either phone is still anybody's guess, but at least the possibilities have been narrowed to $100 or less -- a good idea, since it wouldn't take any sales away from the Sensation 4G if it were any higher.
