I have an iphone 3G. I got it about a year and a 1/2 ago (so Christmas of 2008) and my sleep/wake button has suddenly stoppped working, so I have to wait for it to lock on its own which is annoying. How can i fix it? I don't want to turn it off, because I turn it on using the wake button and what if I can't turn it back on?? What can I do? Would the people at Apple help me?
