Ps. I hope you done some SHSH blobs save, because iPhone 4 and iOS7 Is trash, I am lucky to have a 4s and I can still say its ugly slow buggy trash just trash compared to the best iOS6, in the begin I got all exited but now I deeply regret, especially because there is no coming back for iPhone4s there is still for iPhone 4 but only if you had saved you SHSH blobs, iPhone 4 will become unusably slow with this update, if you lucky and corrupted try still installing iOS6 before 7 I am sure there is a way if its not to late and you just have now a corrupted iOS5,

Cheers

thanks man :-)
