Hi. I have iphone 4 ios 5.1.1 jailbroken. I was fine with my phone until yesterday i off my phone. Off as in (slide to power off) Then when i on it again. It keeps on respringing for how many times i cannot remember. When i try to unlock my phone , it will respring. I dont know what i did that suddenly its back to normal because i just press the power and home button repeatedly. My question is i cannot off my phone at all? Or anyone know why is this happening to me?
