Ever since I updated the ipcc to 5.5, the phone's been acting kinda goofy. It's been a bit sluggish in opening/closing apps. It's hung on apps a couple of times. When I tried to scroll through my iPod song list, the screen starts to shake up and down. When I reboot, the phone won't register my taps to enter my password. After a hard reset, it seems to be working okay, but who knows if symptoms will start again. Anyone else experiencing weird issues like this?
