“I tried to play a wmv video on iPhone 4S, but there is no image, only voice. How do I make it display the video?”, when i browse an iPhone forum. i found this question. And accroding to the information from iPhone 4S official website, it doesn’t support wmv videos.
As you see, we can’t put wmv videos on iPhone 4S directly. In this case, an easy-to-use yet professional WMV to iPhone 4S Converter will be what you need. Like Pavtube video converter or Pavtube video converter for mac. It supports converting any WMV to iPhone 4S MP4 with only three steps so that you could copy and watch any WMV videos on iPhone 4S.
