Hi, I'm having problem with downloading or update from AppStore thru my iPhone 3GS. Whenever I hit the install or upgrade button, the Page will freeze. It will take over 30 mins before it exit AppStore by itself. And the new apps or update apps will appear in grey icon and prompt 'waiting'. It will take few hours before my password was asked. During this period, AppStore will failed to launch as well. But it may not guaranty successful download or update of the apps as well. I had tried restore but problem still prevail. Could the AppStore app be corrupted? Or it is just busy at the server? Anyone facing the same issue? How to solve it? Thanks
