Ready to kick off Monday with some iOS flashing? Excellent, because Apple's just released the second beta of iOS 5.1, lovingly christened 9B5127c. No Cupertino devices at Engadget HQ have taken the plunge, but as noted by MacRumors, the beta enables individual picture deletion from Photo Stream -- which differs from the existing delete all or nothing implementation. Too early to tell if it'll finally squash any lingering battery bugs once and for all, but you can hit Apple's developer website to get your download on -- just be ready for the next one in two weeks, cool?
