How to retrieve Old/Lost photo from iPhone 3G?

So here's the dilemma, there's a picture I need to get off of my old iPhone 3. I have a 5 now that has the same phone number, AT&T is my provider. I no longer have the iPhone 3, and no where on my computers can I find my old iPhone's backups, nor is the picture saved anywhere else. I know exactly when the picture was taken, if that helps at all (over three years ago), and I know that I have sent it at least once as a text message. Is there a way that AT&T upon request can provide the service of digging up the old photo out of my phone or possibly as a a file a transfer? Maybe photos can be retrieved as a part of texting phone records? Any ideas/solutions are welcome. Non-solutions are not, if you think this isn't possible, then please hold your response.

You can use iphone transfer software to copy Apps, Contacts, Songs, Videos, Photos, Playlist, Games, etc between iphone and computer. Here's the one I used to use

  • Why is my photo transfer from iPhone 7 to Mac missing many photos and how to I retrieve them? I had resriction codes I wanted to get rid of so I backed up my photos with the help of apple assistance, and AFTER I restored my phone to a new phone I noticed there's a big gap of missing photos. It isn't that it only saved old photos, because iPhoto has my most recent photo, but before that is missing 4 months of picture, please help me.

  • Is it possible for me to retrieve my lost iphone? So basically my phone is an iphone 5 and it's updated to the recent update of ios 7 and I only just realised that I didn't activate my icloud account and there's no lock on my phone… What I was wondering, would i be able to trace down the thief even if they deleted my icloud account and changed it to theirs and did the whole restart process ( i think it's called restoration system something ) and inserted their own sim and take out mine… Please help!
