MP4 file in iPad2
I read someplace that iPad2 will play .mp4 files, so I e-mailed a file to myself, opened it in "Mail' clicked the file to download...and it seemed to download. However, I cannot find the file in Music, Videos, Photos or any place like that. I have read since that iPad2 will only plaay mp4 files in iTunes format.True? Other questions:
1. Where did the downloaded file (25 mb) go? I want to delete it....and how do I do that?
2. Had I had the VLC Media player app installed, would IT have played it? Or must it be converted by some iTumes app...and which app is that?
3. My grandson a couple of thousand miles away set up my iPad2 on his laptop, so I don't have access to his iTunes, nor do I have a PC with iTunes installed. I have only had the iPad for only a month.
Thanks
iPad 2, iOS 5.0.1
