Something is completely wrong with my iPhone 4. It never launches any app, it just black screens then it goes back to home. The only apps it launches are the built in apps. Anyone help please? Thank you in advance if you did help. )
Those are pirated apps. Get rid of them. And it's too sad all of your non-system apps are all pirated.
Not necessarily. I don't know what made you quickly come to that conclusion. Try restoring. I would first restore to a backup and see if that works and if it doesn't do a clean DFU restore.
Experience. I had the ********** app when i got my first iPod (back in 2008) and stopped 2 years after.
