I found what I thought were threads similar to my problem, but didn't seem useful. Basically, my sleep/wake button is stuck on my iPhone 4. There are moments where it'll pop back and I'm able to actually click it but a lot of the time it's just stuck. For whatever reason I am attributing this to the cold weather, but I have a bumper on it but I was just wondering if there's a good fix (an object to pry it out) or just take it and get it replaced? I did try to clean it and it didn't seem to be dirty. I wish I knew what was causing it. Thanks.
Edit: It's not a huge deal, btw, since I'm still able to put the iPhone to sleep and wake it up, but it's a little annoying. Thanks again!
