Flaky iPhone 4 Home Button
I've got an iPhone 4, and for a while now the home button has been quite unresponsive. Sometimes I need to press the button around 5 or 6 times for it to register. However, I noticed that once I restore it to factory settings, the home button goes back to normal.
Once I put my apps and music on the iphone once again, the home button problem reappears. Has anyone heard of a problem like this, or is it just a coincidence? What can be done to fix it? Should I reinstall iTunes and re-download all my apps?
