My ipad was on 6.1.3 and I thought to see how beta 5 works and I downloaded the file, IT WAS A DMG FILE anyway... I exteracted the files and found the ipsw, shift+update through itunes. When I unlocked ipad with ios 7, the keyboard was well... it took me 5 minutes to put my password (about 15 seconds for every key) Why is beta 5 so slow? the animations were perfect, smooth as butter.
