I got the update yesterday. Before the update, I could play videos from a friend who has an iPhone. The videos would play fine. However, when i get an email from them now with a video attachment, the video will not play. I tried to play a video that I was playing prior to the update and it will not play now. The video has .qt at the end so I assume it is in quicktime. It will play on my computer on quicktime but not on my phone. How do I fix this?
