Some guys over the Samsung website today accidentally posted an image of Samsung Solstice, a not yet announced phone, on its AT&T partner page. The Samsung Solstice appeared to be a touchscreen phone powered by Samsung’s TouchWiz user interface. Since the Sostice phone has AT&T logo on it, we should expect AT&T to announce the phone very soon. Other sources on the Internet say that the Solstice phone will be annonched on August 2nd, however AT&T doesn’t confirm that. Its release date remains a mystery.
