Frame load interrupted error while loading a word document in UIWebView
The reason was, the file I tried to load doesn't contain a extension. I was purposely removing the file extension (.doc and .ppt) which I think confused the UIWebView. Seems like iPhone ignores the OS 9 legacy typecodes completely. :)
I submitted a Radar regarding this issue. It's resolved in the latest version of iPhone OS 4.0.
