Has anyone else experienced this? Ever since upgrading my iPhone to iOS 5, I've found that when using inline headphone controls, such as play/pause, etc, they will frequently glitch. I'll press the button, and either nothing will happen, or, my music will pause then begin to play back on its own. Or, sometimes, I'll press the button, it works fine, but then a moment later the music will just start pausing all on its own. I have experienced this with any iPhone hardware running any version of iOS 5, including beta/developer releases. I've also tried different headphones and attachments, and it still seems to occur. However, the actual iPod software works perfectly: if glitches occur, I can always just use the software buttons. Just curious if anyone else has noticed this, and if anyone has found a viable solution?
