I have an iPhone 4S and when I went to wake it up with the sleep/wake button I noticed it didn't make a clicking sound like it used to before. It seems like it's stuck and requires a decent amount of pressure to get the phone to turn on. Is this a problem that can be fixed by myself? The nearest Apple store is about an hour away so I really would like to save that as a last resort. Edit: Called the world's best customer service and they're going to replace my phone for free. To anyone with this issue: if you're still under hardware warranty, call Apple and it's a free replacement.
