This is a a sort of strange question, but it actually leaves my RELATIONSHIP with my Girlfriend hanging in the balance! Years ago, I made a video on a 2008 iMac, in Photobooth. I then used a usb drive to move it to a Macbook. Recently, I emailed the file to myself, so that it would be on my iMac again. Now the video file ends in "-iphone-cell.3gp" despite having NEVER been on an iphone. I can't explain it. Oh, the reason it affects my relationship? It was an old sextape, and now my girlfriend thinks its recent because I never had an iphone until recently. Help?
