How to restore my iphone apps, picture and videos?

So I was trying to find my friends iphone with the "Find my iPhone" App and for some reason it completely rebooted my phone and deleted everything!

My pictures and videos are VERY VALUABLE to me and I can't seem to recover them from itunes because I didn't lose my data from an update.

My question: How can I restore all my pictures/Photos?

If you have backup of it on iTunes:

1.) Plug it into iTunes
2.) Right click on its name (on lefthand side)
3.) Select restore from backup wnd choose your iPhone's
4.) When done, everything from your last backup should be there

If you don't have backup:

Taking it to the apple store is your best bet.

You can try the professional iPhone Backup Restore software that can help you extract iPhone data like photos, videos, SMS, contacts, notes from iTunes to computer one by one. Here is iPhone Backup Restore download page, you can try the free trial version

I have ever met that similar problem last week, too.
I use iPhone 4, and I do want to get my lost videos and pics back.
then I googled for the answer, and this guide helped me solve the problem.
you can take a look if you need, hope this can be helpful for you.
