My iphone has been acting up a bit lately. Sometimes, when its half charged or more, it will cut to the connect to iphone picture and show a red lifeless battery. So once i turn it off and on again, the battery goes back to normal. Alsol it gets really hot. Do you think i could just do a full restore and take it down to apple and exchange it? Ive previously jailbroken it and dont want them to somehow find out that i have. Any thoughts? Thanks in advanced.
