Hey guys, I have the new 3.1.2 update on my 3gs which I got a few months ago. I used RYP(Rock your phone) to install Winterboard thinking it would work. It asked to reboot my phone so I did, and now every time I try to turn it on it goes to the apple icon for approx 30 secs then the screen goes black. I have tried multiple times already. And better yet, my iTunes won't recognize my iPhone so I can't get it to DFU mode... Any help is appreciated!
