Yesterday i had a problem with a iPhone 4(4.1) so i decided to restore it. After a few problems, i finally restored it to 4.1. Then i jailbroke it again and installed AppSync. The problem came when almost every jailbroken app didn't show on the spring board, but iTunes said it had been installed. When i viewed my springboard in iTunes, i saw that there's a white blank home screen and the apps from the next screens were installed too, but they didn't show up. I restored it again, factory restarted it, treid to move the blank screen and the apps but nothing happend. What should i do? Please help.
