IPhone 4 keeps restarting, I'm desperate for

I have a black iPhone 4. I put it on charge a few weeks ago and ever since, its not working. It comes up with the lock screen like normal (hence I can still access the torch, airplane mode ect) but then as soon as I put my passcode in, it shows my wallpaper for a couple of seconds then restarts itself. I have tried to restore it but I can't allow access to iTunes because I can't get off the lock screen to allow it. I have very valuable pictures on this phone of my son and our recent holiday.

For an unlocked iPhone, how much?

I'm thinking of getting an unlocked iPhone then hooking it up to a network? I know it's expensive (initially) but eventually won't it pay for itself? Or honestly, is a "plan" so much better? I mean you could purchase packets of data (if you need it) or just remain on Wi-Fi only, right?

Why isn't my iPhone playing music through my car s radio anymore?

I have an iPhone 5c, and for a while I've been using my Pandora app to listen to music in my car. All I've had to do is hook my iPhone up to the USB port in my console, and press the AUX button on my radio; I got in my car today, hooked my iPhone up with the USB, clicked play on Pandora, and nothing happened. The volume was on, and if I unplugged the USB my radio would show a prompt saying "USB removed", but when I plugged it back it the prompt "Sync line in" would remain on the radio and my music wouldn t play through it; even when the phone was clearly hooked up ( registered as charging), and playing music with the volume up on itself and the radio.

Is the otter box defender series worth it?

I had an otter box defender series for my iPhone 5 and I liked it but the screen protector over it would prevent me from touching the screen. I d have to apply more force. Now I have the iPhone 6 and am thinking about the otter box for that but I still fear the same issue. And some reviews I have read say that the buttons are hard to use and the touch ID doesn't work good with it. Right now I have a ballistic case which is comfortable and I like it I just wanted something more protective. Should I stick with the case I have or get the otter box?
