My touchscreen is complete unresponsive as far as trying to tap to open anything on the bottom row like Phone - Mail - Safari - iPod as well as when you are in an app. But I can slide to unlock without an issue as well as scroll the multitask bar - yet cannot tap anything. I have tried to restore from backup as well as set up as new with no results. Literally phone was working flawlessly. I had ust typed sent someone a message and went to another text to respond and suddenly that area was dead. Was wondering if anyone has run into this problem before. Thanks in advance!
