I accidentally deleted my Facebook lookback on my iPhone 4s, I really want it back. Please help?

If you used Chrome when you watched your video prior to deleting, just do these:

1. Type about:cache on your chrome search bar (provided that you don't clear history/cache after you close your browser)
2. You will see a list of links on your window, just click Ctrl F or ⌘ F to and search "lookback" in the Find searchbar
3. Look for the link that will have something like https://lookbackvideo7-a.akamaihd.net/hvideo and so on. Click on that
4. After you clicked on the link, you will see on your window a bunch of text with white background. Ignore that. LOOK AT YOUR URL BAR. You should be able to see something like chrome://view-http-cache/https://lookbackvideo7-a.akamaihd.net/hvideo-ak-prn etc etc. DELETE THIS PART: chrome://view-http-cache/ then press enter.
5. You should be able to see your video again. Right click and choose "Save Video As" and just reupload on your Facebook timeline, Youtube, or anywhere.

If you didn't use Chrome, I think you can access your cache data via C:\Documents and Settings\Local Settings\Temporary Internet Files. It should be an MP4 file.
