All I know is 3.56 borked my shit. I don't do custom firmwares or hacks or any of that shit. It refuses to finish installing, sitting at 99% for hours and hours. Rebooting just sends it straight back into installing, which reaches 99% and stalls. I shoulda downloaded 3.55 when I had to chance so I could downgrade using recovery mode, then at least id be able to watch movies.
