[Advice] Need to recover lost pictures from restored iphone, is it possible?

first of all let me say im a PC guy, so im used to being able to easily recover data that has been deleted, overwritten or even reformatted. im pretty sure its a little more difficult to do in the unix family but i just thought id try

i have a friend with an iphone who took some photos that we really need. unfortunately somehow the phone "died" - it was frozen or stuck or something... so the apple people did some kind of system restore to return it to functionality and in the process all the pictures are gone... (should have brought it to me first)

now that the iphone filesystem has been hacked and it can be accessed as a drive, is there any chance i can somehow recover those picture files? is there any program/utility that will let me do this? (like on a PC i generally use Runtime's GetDataBack software...)

Hi,
Have you solved this issue yet?
I have been trying to work this out using the following method.

-from the iphone I make a dd image of the iphone and ssh it to my make.
dd if=/dev/disk0 | ssh <username>@<computer-ip> 'dd of=iphone-dump.img'

-this gives me a 15.12GB image of my iphone hard drive

- in theory, I want to now mount this image and run a recovery software on that mounted drive.

my problem is that I can't mount the image. Under OSX i get the error "no mountable file systems". I get a similar error trying to use the mount command at the terminal.

I wonder if anyone has any ideas to help out.

thanks...
