ok well I have an unlocked/jailbroken iPhone with tmobile service. I've had it for about a month and havent had any problems with installer until now I was on installer a few days ago and something popped up asking me if I wanted to update installer, so I accepted. Ever since i got this update, installer hasn't worked. Everytime I click it, it goes to a white screen for a few seconds and then goes right back to the home screen. Idk what to do, can someone please help me?
