There is something wrong with my iphone 4. eevery time i play a video (podcasts still work, youtube still works), the black screen comes up but then it freezes and after about 1 minute the iphone resprings. Now I have tried restoring and this has not made a difference, but then I have realized it is some mobilesubstrate addon causing this problem, as the video playback works if i enter safe mode, otherwise, no. I will put up a list of my installed things later but I was wondering if anyone knew which was the app causing this problem? Thanks EDIT: alright found the problem - multimusicinfo. What a waste of a restore... i lost all my contacts and everything as well =="
