I used ziphone to unlock and upgraded to 1.1.4 and iphone worked fine for a few weeks. Then the touchpad stopped working. I restored to 1.1.2 and unlocked with ziphone and it worked ok again. Now about three weeks later the touchpad is not working again. I've tried to restore to 1.1.2 and 1.1.3 but this fails in iTunes, only 1.1.4 restores - but the touchpad still doesn't work. Any ideas?
