In the past 24 hours I've flashed to 7/22, then 7/27 last night around 11PM and now I'm flashing to 7/28
It just booted and the start animation/sound was not choppy anymore. Looks good!!
EDIT: Holy crap my cabs installed FAST!!!! I installed the clear-flippers cab, HQ wallpaper cab, default WM messaging cab and Psyki's glass theme cab - all of them zoomed by much faster than last night's 7/27 build.
