When I started up cydia today, there were some upgrades available. I can't remember which ones, but after I installed the upgrades, I had to reboot. However, my ipod touch refused to reboot all the way. It turned off, got to the apple logo and then turned off again. Trying to turn it on manually yielded the same result. Yes, I've put it into DFU mode, but it's annoying that I have to restore, lose all my data, and that I have to jailbreak again. What I want to know is has this happened to anyone else? Any ideas on what may have happened or how to prevent this from happening again? Thanks.
