So i used greenpoison to jailbreak my iPhone 4 running 4.1, and it worked great for a few months. Today I decided to update to the 4.2 and run the new greenpoison jailbreak (which i have used on my ipad with success). However, i did it on my iphone, and now when i open cydia, the screen goes haywire and the apple logo comes up on top of the screen, with a loading bar underneath it. I am able to close cydia and move about the phone, but the apple logo + loading bar remains on top (almost transparent but not really) Any clues as to what is going on here? And is it bad? Never had a problem like this. And it seems like it takes longer to reboot with the new iOS and jailbreak. thanks.
