My home button intermittently stops working (iPhone 4)I've tried the following fixes: Sync- fixes it for awhile Turn off and back on- sometimes fixes it Deleted files to make more room- no change Restart- can't when the home button isn't working but I restart frequently when it is and seems to make no difference Complete restore using a backup- no change. My last effort will be to restore to factory without using a backup copy. I'll download all apps fresh from the App store. Any other suggestions? Thanks!
