Broken Hearted Son...Help please.

All his summer trip pix gone. Here's what he did: Is there any hope of getting them back?


1. plugged in phone to PC.

2. opened up iTunes

3. right-clicked phone in iTunes sidebar

4. chose to restore from back-up (had not backed up vacation pix)

5. picked back-up titled iPhone 4

6. received a pop-up stating that only the contacts, messages, notes, would be affected, and nothing else

7. phone restored from back-up

8. when I checked the phone, I had my contacts back from the previous restore, and my current apps, but only 204 of my 550-600 pictures.

I checked Picasa and there wasn't anything there

I had iCloud enabled

I'm not sure if I had iCloud backup enabled.

Any help, directions to software or experts who can help save his memories would be greatly appreciated.
thank you.
