iphone4 sync -Lost photos

Hello,

I tired to sync my iphone 4 (with 200 photos from Halloween/weekend) on my boyfriend's PC's itunes where I accidentally clicked "restore to his itunes " and thereby lost all photos on my fone.
IS there a way in which I can retrieve the photos? Is there a back up for these photos on my iphone?
Please tell me there is.

Thanks so much.

Did it happen to run a backup when you initially plugged it in, like how it automatically syncs when connected? If it did then you should have your backup and be able to restore to that backup and have the pics there. If it didn't do that before the above happened I don't personally know of another way.
