How to restore photos from iPhone 5?

I've got an iPhone 5 fairly recently and accidentally deleted quite a few photos and really want them back. The problem is I'm travelling at the moment so haven't made any backups and rarely at Wi-Fi spots so Photostream, Dropbox and stuff like that hasn't been an option.

I've been reading about general photo recovery software - like for SD cards - and have used one before that worked for an SD card, do they work for the iPhone 5? I've got no backups and really want the photos back.

Is it possible, if so, how?

Without them synced or backed up via Dropbox (or similar service) there's no way to recover deleted photos off an iPhone. Sorry.

Take care,
