This morning the home button on my two year old iPhone 4 stopped working. I tried the rebooting and the software “recalibration” fix involving going to the “slide to power off screen,” but it didn’t do anything.
Some people reported that a bit of isopropyl alcohol on the button would do the trick so I put a drop or two of 91% isopropanol on the iPhone button and pressed it a bunch of times and it was fixed right away. I wouldn’t mind an excuse to open the phone, again but there was need to replace hardware this time.
UPDATE: The fix was short-lived. Blowing vigorously into the dock connector seems to help, possibly clearing dust out of the button.
UPDATE 2: Still kind of flaky. I ordered a replacement button.
UPDATE 3: Replacement button installed and working, what a difference!
