So I've got an iPhone 3G running 2.2 and it's jailbroken. I recently ran into a problem while trying to stream video through Safari. Usually I can play a video through Safari as long as it's compatible (i.e. not Flash). But recently I tried playing the same type of video that used to work, and now instead it shows two buttons, either watch or download. Both give me errors like the video is not compatible and won't play. I think it's very likely because I installed some third party app, but I've uninstalled anything I thought it could be, but I still have the same problem. Any ideas how to fix this? Maybe an app I'm missing to uninstall?
