My iphone 3g keeps freezing on the lock screen without the time and whenever I try to click something it doesn't help. I've tried shutting the phone off completely and restarting it and I've also tried a hard restart and yet it's still doing this. I updated the new rock app yesterday and that maybe the issue but i'm not sure how to go about getting rid of that and downgrading the rock app and even so it's hard for me to get to my home screen unless I restart it and for a couple minutes it will work again and then go back to this.
Please help me I'm leaving the country very soon for 6 months and taking this phone with a new sim card so I really need help ASAP!!
