The AT&T Galaxy S II launching Sunday has faced a stumbling block through a major security hole shown on video (below). Anyone can bypass the password or pattern unlock just by waking the phone, letting the display sleep, and then waking it a second time. BGR notes that the only safeguard is that it requires the phone having been properly unlocked at least once before, although that's very likely to be the case for any system that hasn't been very recently rebooted.
