so i jb'd my phone after the update, installed iblacklist then it asked me to reboot device. buts its a tethered jb so it just got stuck on the apple screen. so i used redsnow to boot tethered, but now whenever i open any app, the screen image gets small and sits at the top left. has anyone ever had this problem? how can i reboot my phone safely after a cydia install on a tethered phone?
