latest os blackberry 9900

1) BBDA was on my mine, no problems there, even upgraded it for me. 2) everything is much snappier on this OS, from screen to screen, min and maxing, everything is much 'zippier'. 3) can't comment on battery yet, altho did go to bed last night and it was at about 50% which is pretty high for me. power bank samsung 9900 mah
