Hello ! i have recently updated to 4.0.1 from 3.1.3 after jailbreak and few installs from cydia my background stopped working. The homescreen background stays black no matter what wallpaper i choose ( from within the ios system ). Simple background does not work though it says on cydia its working perfectly and with bosspaper on i cant see my multitask dock ( it shows the lower part of the wallpaper but not icons no nothing ) I uninstalled winterboard and simplewallpaper and still got the same problem. Ive only got infinidock ,infiniboard and sbsettings installed...

Also, sometimes when i want to unlock my phone from standby my screen opens for a fraction, closes then opens again to the lockscreen.

Does anybody know what to do or had\ have this issue ?
