Iphone 4 help, Can't export (share) mp4 videos?

I downloaded a few mp4 videos to my iphone, but i can't seem to export(share) them. They don't show up in my "video" folder, but if i search the phone for "videos" a video app shows up with the vidoes in them. I can play them but i can't do anything else.

It is because you need to get rid of that junk apple phone and get a DROID platform cell phone. Like a Samsung Galaxy S-3. OR Anything DROID. I was in your shoes and drinking the apple cool-aid, for many years. Problem is even when you buy a Apple product, they think they still own what you bought and anything you put on a iPhone. That is why me and 30 million other people switched to a DROID in 2012 alone. Try the DROID platform I mentioned above. You will never have these problems with movies, music or any content with a DROID phone. Not to mention but 99% of androids apps are free as well. Full games and all. Poor out the "apple cool-aid" and move over to DROID. As you will be much happier in the short and long run.

Try using the free mailVU app. Works well for me.
