I've been playing around with EH17 most of the night. was stable for a few hours. starting installing my normal round of apps. think i might've messed it up with galaxy tuner, since it doesn't support gingerbread. a little bit after that it seems like my phone turns off by itself when I turn the screen off. did a restore from right after flashing it but still does it? should I go back to step 1 with odin and pick and choose carefully apps?
