Hello, I just jailbroke my iPhone a couple of days ago. I knew some cydia apps I wanted, open ssh, backgrounder, winterboard etc. After downloading a file in cydia one time, my iPhone said updating data and there was a spinning wheel, but it just kept spinning and my phone didn't respond, i couldn't even turn it off by holding the power button? Just wondered if anyone else have this happen or if someone knows what causes this? And what do you do if it happens? I eventually rebooted my phone but I am asking in case it ever happens again. Any help?
