My Instagram won't let me log in at all

I logged out of my instagram from iPhone 5 so my friend can get on. But when my friend tried to log in she said that her account was disabled and when me and my sister tried to log in, it said the same thing. But when we logged onto my sisters galaxy S3 it worked! I deleted the app & downloaded it a lot already. I also reset my phone multiple times and reset the passwords like 5 times.

Distracted drivers. Digital billboards?

Don't text and drive. Right? Well then take down the digital billboards so I'm not typing in the number for a cheap estimate on roof repair into my iPhone. If distracted drivers cause accidents then stop distracting them. The world makes no sense anymore.

How to jailbreak/unlock iPhone 5?

I have a new iPhone 5 now, but my country region does not support ANY Apple services (iTunes, App Store, etc.) I have to jailbreak or unlock it! But HOW? I can't even download ANYTHING with it! How do you do that? It is iOS 6.1.3.By the way, does iPhone 5 need a scratch resistant screen protector? Cause my iPhone still has these plastic covers that were on it when I took it out of the box and should I peel them off and get a protector or not?

Iphone update with itunes deleted photos?

Okay so my brother has an iphone that he had never plugged into itunes before. The phone was becoming slow because he had never updated it. I plugged it into itunes and a messaged popped up saying "back this iphone up to the computer before update? This includes contacts, photos etc." so i clicked okay and then started the update. It was about 45 minutes through the update that my dad accidently cancelled it and we had to start the update again. When it was all finished, my brother opened his phone and all his photos, contacts EVERYTHING was deleted! I tried syncing the phone but nothing was synced back onto the phone: L!
Could the contacts and photos be stored somewhere on the computer prior to the cancelling of the update? Oh and i also tried to restore the back-up and it didn't work!
any help would be much appreciated. I'm not real computer smart so please help!
