After updating to iOS4 my iPhone has trouble going into landscape mode, I have deleted all settings and restored the iPhone. When I go to the calculator application and put it sideways it does not go into landscope mode. However, If I shake the iphone sideways it DOES go into landscope mode and if I shake the iPhone again it will go back into portait mode. When I play games such as backbreaker the game works perfectly and I have perfect control of controlling the iPhone. I would like to know some feedback or troubleshooting methods I could do. Thanks Guys!
