IPhone 4 spazzing out

Hi! I have a hand-me-down iPhone 4. My dad had it, but he got the iPhone 5 so he gave it to me. I was playing a game on it and then the screen froze and started making the screen that has the loading circle and it has that black screen for about 5 minutes. Then, it gives me my home screen, but the "slide to unlock" part if frozen and it goes back in the load screen after around 10 seconds. It's been doing this for 30 minutes and hasn't stopped. I've tried charing it, and it makes the buzz that means it's charging, but it doesn't help. I've searched on google and I couldn't find anything (probably because I have no idea what's wrong.) I don't think my phone is broken, because I had an iPhone 3G ever since it came out and it hasn't done this. So basically, does anyone know if I can help it? Or is it ruined?

Will i get caught using a blacklisted iphone 4s?

I found one but it is blacklisted, i wanna use it as an ipod but i was wondering if i could get caught by putting the sim card in and leaving it there. I hate that no sim message. Phone i already activated

Retrieving photos from stolen iPhone?

My iPhone was stolen about six hours ago and I was just wondering if there was any way I'm able to get back the photos that were on it? I last synced my iPhone to iTunes about twenty four hours ago, but am not sure if I'm connected to iCloud or not. Is there any way I'm able to get them back through iTunes or does anyone have suggestions on how I would be able to get them back another way?

Iphone 5 Supplier? Is it a scam?

Here is an email i received.
I was also shown their company's certificate when i asked.

IPhone/iTunes Album Artwork problem

Had my iPhone for months and a music library on iTunes and the phone in the 1000s and nothings been wrong but yesterday I plugged in my iPhone to charge on my PC and it wouldn't sync it popped up saying ''iTunes can't read contents of the iPhone, please restore'' or whatever so I chose not to because I would lose my stuff so I just downloaded iFunbox and deleted the music file which was recommended by people to do with the same problem and that worked fine and it deleted the music from my iPhone but at least it was out of recovery mode and could be synced now

Spent HOURS syncing the right music back on to my phone and once everything was done I plugged it out and not a single song had an album cover, I've bought my fair share of iTunes music but most of my library are downloaded MP3's. Whether I bought it from iTunes, used 'Get album artwork' or manually put in a cover on 'Get info' every single song I had had a cover and now on my phone none do. Not my ones or the Store ones.

But the thing that's annoying me is that on my actually iTunes music library everything's in tact with all album covers, I've tried EVERYTHING I've cleared my phone and tried syncing several times to my library and its just not working.
