Recovery of wiped iphone data

Hey guys!

First time posting here but i thought i would ask the pros.

I recently came back from a conference which i took a load of important videos and photos at. When i came back home i tried to import the photos and videos onto my computer so i could use them for work.

Itunes said i needed to update my iphone, so naturally i hit yes. After updating itunes said that the phone had an error and it had to be restored. So with out having any other options because the phone wouldnt seem to work i hit yes.

Everything was wiped!?
Ive looked in the itunes back up folder and can not see any of the recent photos, videos from the conference not to mention all my business contacts and notes..

The question im asking is - Is there a way to recovery data from an iphone 4 after it has been deleted.

I havnt sleept for days because ive been doing a bit of research..
Heres some info i found

"Now you are probably wondering how its possible to retrieve photos off your iPhone that you've already deleted. Well to give you a quick answer, your iPhones hard drive is very similar to a computer's hard drive. And just like a normal hard drive the iPhone doesn't delete media or pictures off its hard drive permanently, instead when a file is deleted its space is just listed as available and new re-usable space."

Ive tried the program which is mentioned on the above web site but it doesnt even pick up the iphone when it is plugged into the computer.

So my question to everyone is, is there a way i can forensic recover the data as it sounds like it is still on there but just "hidden"

Also my iphone is displaying 14gig of data used when i plug it into the computer but i cant seem to find where this 14gig of data is on my iphone which makes me think it has been moved/hidden to another location on the harddrive of my iphone.
