Help IMMEDIATELY! Jailbreaking iPhone 4S with iOS 8.1.1 went terribly wrong?

So I was trying to jailbreak my iPhone 4s with the iOS8.1.1 but while Cydia was doing that filestreaming thing, I accidentally pressed the power button and suddenly it stopped and rebooted and when it came back up, EVERYTHING WAS GONE! All I can do with my phone now is message and call, but pangu is still there but cydia is no where to be found. What do I do? I don't know if I should just try to unjailbreak or try to re-download Cydia but even if I do, my app store and contacts and everything else is STILL gone! What do I need to do?

Is my iPhone 5 that I bought online Factory Unlocked?

I recently purchased a factory unlocked iPhone 5 on the web, on the description it said "Factory Unlocked" and when it came in, and I tried to connect it to iTunes, it says "SIM Card Required" and I can't get passed that screen.

Does that mean that it is unlocked and that all it needs is a SIM Card?

I also have an old Cingular SIM, which I just discovered is not compatable with the current iPhones.

If I get a new Nano SIM, will ATT charge me for the data plan? & will I be able to stick to my current plan with my family?

Transferring data (& iTunes, iPhoto etc.) from old spoilt mac to new?

Hi, I got a new MacBook recently but all my data and my iTunes & iPhoto library are in my old one, which I can't even start up - it's completely unresponsive when I try to turn it on. And unfortunately I didn't back it up while was still working, even though it was clearly steadily deteriorating even after I got it repaired once… Do I have to get it repaired again in order to retrieve all my data? Apart from the data, is there a way to start up my iTunes library exactly the way it was before (I had 600 songs but the files are all in my old computer…) so I can regularly sync it with my iPhone again? If I'm not wrong, iTunes only syncs in one direction, so do I have to wait until I can use my old computer (and how do I do so then?) Any related tips are greatly appreciated!
