How to restore my iPhone 4S? - 1

So last night, I put a pass code lock on the phone and then forgot it. The iPhone became disabled an told me to connect to iTunes to recover. It wiped everything out including my contacts, pictures, apps, and everything else I had on the phone. I wouldn't care if it was my phone but it's not mine, (it's my brothers) he doesn't know yet. So I'm pretty much wondering how can I restore it?

If you haven't backed it up, you're effed. Your brother probably has iCloud enabled so it'll automatically backup… Just pick "back up through iCloud" when you begin your iPhone. If you have iCloud disabled and haven't backed it up on itunes, good luck.xP
