I forgot my iPhone passcode so I restored my iPhone & lost everything

I'm 15 years old, I was stupid and made a really long passcode for my iPhone & then forgot it the fourth time I tried to type it in. So I restored it on iTunes and I typed in to back up all the information but I lost my contacts and all of my pictures which really sucks! The music I got back since I only have 131 songs on it but I didn't really care about the apps but I lost all my contacts, Is there any possible way of getting them back? Please help! I won't die without them but it would be really nice if I can get them back.

How much for an IPhone 4S from AT&T?

I have a regular messaging phone from AT&T with unlimited texting and plenty of minutes per month, but no Internet. There are 3 other similar phones on our account.

Do normal iPhone cases protect the iPhone?

I know Otterboxes are your best bet, but they're so expensive.

If you just bought a normal, plastic iPhone cover, would it protect the phone if your dropped it?

Would this break?
Would it protect an iPhone from cracking?

Where to buy iPhone 3 cases?

I have an iPhone 3gs and I need some nice girly colourful covers for it. All the cases at Claires are for iPhone 4. I can't find them anywhere. I already checked H&M and f21. Plus the ones at nordstorm are really expensive. I'm a 16 year old girl and I'd be using my own pocket money so anything under $20 would be great.

Also, where can I get a decent and cheap laptop cases. The ones at Claires are $45.

Everytime I turn my laptop on, it stay as just a blank screen?

I was on my laptop last night (Acer Aspire 5535, Windows Vista. Just incase any of this matters), and when I was finished, I put it to sleep as I usually do, because turning it off and on it so much effort. Maybe that's what caused the problem even though I've done it for years.

Anyway! This morning, I turned my laptop on, and the On light, the battery light and the charger light all showed up as usual, the fan was going and I heard something from the disc drive… But then nothing. The screen just stayed black and it wasn't loading. So I turned it off by holding the power button, and back on and the same thing happened.

Did a bit of research from my iPhone, and did that thing where you take the battery out, and unplug the cable, held the power button for 60 seconds and then plugged the charger back in, left the battery out and turned it back on. It worked fine after that.

Only problem is, now EVERY TIME I turn my laptop off or put it to sleep, when I turn it on, I have to do the 60 second power button thing. I also noticed that my web cam doesn't seem to work since today. It tries to work for about 10 seconds and then turns itself off again.

Any help with this would be great!

Thanks guys.

Also, just want to add, I put a question on a few weeks ago about VGA not working from this laptop anymore. Do you think my computer is just starting to fail and die?
