For the past few days my iPod touch hasn't been refreshing in installer, it tries and a very smaller portion of the loading bar shows up but then it stops and i doesn't do anything. When I try hitting the home button it doesn't do anything. I have to press the home button and the sleep button a few times before it goes to sleep mode. It has done this before but I just retried later and it worked. I don't know what I should do. Anyone else having this problem? And what should I do? Also what do you think is causing the problem? Thanks to any support!
