I am having a problem with my Iphone. For some unknown reason it will not let me reply to text messages. I am able to look at all text messages but it wont let me bring up the text message box to reply. On top of that when i try to dial calls direct the numbers 4-6 wont work. Now I orignially thought that it was just broken parts on the screen, but i am still able to slide the bar at the bottom and access the icons in the middle while on the home screen. So this is only on select apps. If anyone has any idea on how to fix this please let me know. I am a major texter and going a day with out texting is going to be hard. Thank you for all who reply.
