Deleted Photo/video

[KoA]

Ok so I had recorded a video on my 3GS, it was about 45 mins long and 1gb.

I was transferring it from my iphone camera on my computer to a folder on my pc. Once it finished loading and saw the file there, I deleted it from the iphone (just pressed the del button on my keyboard over the the video)...

But I guess it hadn't transfered correctly, and the video isn't there.

Any way I can recover it? I still haven't reloaded my phone or anything so any tmp data is still there.

Unless you have managed to overwrite ANY of the sectors where the file was stored it is possible.
Just follow instructions here:
How To Recover Your iPhone Files, Photos, Contacts, Notes, SMS, Call History, Etc.

if recovery on the iPhone does not work - then with a bit of luck the "copy temp file" on the PC might be recoverable

I never backed it up on my computer so I doubt that'll work?

And what do you mean by copy temp file?
