I lost my phone icon for my iPhone 4. I tried a reset - holding the sleep button and bottom button. It rebooted, but the icon is still gone. Everything else is fine. What do I need to do to get the phone icon back?
Did you possibly accidentally move the phone icon into one of your folders? Can you still dial out using one of your contacts? Check these things before restoring a backup from your itunes (assuming you made backups).
