ITunes keeps kicking me out

A few weeks ago I got into iTunes and It kicked me out of the app I tried turning my phone off and on I tried deleting all the apps from the multitasking but nothing is working. Btw it's an iPhone 4 and it has iOS 7.

What to do with blacklisted iPhone 5?

I was on T-Mobile for a couple of months and I had horrible service. I had no bars in my house and had to walk to the end of my backyard to send a text or a call. Text or calls were not received. I called them around 10 ten times. Each time it was "the tower is broken" or something completely different. I asked for signal booster, never got it. I decided to leave. I was not going to pay tmobile $1500 for the 3 iPhones so I just asked at&t and they said I could go to them and the iPhones were unlocked. So I ordered the sims. When I put them in it won't let me. What can I do with these phones? What do I do? I'm not paying them.

IPhone 4s won't send iMessage?

I got my iPhone 4s about 7 or 8 months ago and it's in really good condition. It's never been dropped. It has no problem connecting to Wi-Fi but I always have the cellular data turned off because I have a 2GB limit. Even with the cellular data turned off I've never had problems sending messages using the Wi-Fi at home. The problem started about 2 weeks ago. Every time I try to send an iMessage it sends about 90% but then it just stops and does nothing. After it stops I send the message as a normal text and it works just fine. I do know for a fact that my phone has issues and everyone else's is fine. I have had ios 7.0.2 since the launch date and didn't have any problems at first. I have my iMessage set up to send/receive from my phone number. I don't have my e-mail set up on my phone. Can someone give me any information on how to fix this?

How to protect myself from being spoofed?

When I went to my school and used y computer a friend of mien was spoofing me so what most images I saw were changed to ones from my little pony. Hilarious I know. We both have this thing going on related to hacking, but we try to not hack each other, this time he did.
I was just wondering if there's a way I can protect myself of this or I can actually do the same to his computer. He uses a kindle that has d-sploit and network spoofer. I only have an iPhone and a computer with windows 7 and Kali Linux. Is there a way in which I can get him back?

So my 2 main questions are:
1.Is there a way I can protect myself from being spoofed.
2. Hoe can I also spoof him in this way.

I have hardly any space on my iphone?

I have an iPhone 4 8gb and I don't even have 1gb of space left! I used to have heaps of photos, music, and apps but then I realised that I was running out of space so I deleted most of my stuff. I regret buying it (only because of the gigs) but now I'm stuck with it because I'm on a plan:/ I bought it 4 months ago and I've still got ages to go in my 2 year contract. What are some ways to save space until I can upgrade to a better iPhone with Way more gigs? I use my 32gb iPod touch and my iPad to plays games/download apps because I can't fill up my iphone. I hate having to worry about filling up my phones space.

2010 Audi a4 and iPhone 5 connection issues?

I got a 2010 Audi a4 about a week ago for my first car and I love it! The only thing is that I'm having issues connections my iPhone 5 to the AMI in the glove box. I have a premium + without nav if that makes any difference. The thing is I have two wires coming out of the glove box, one for the last iPhone models and one for aux. I connected my iPhone 5 to the aux and nothing connected. I then tried my brothers 4s and my ipad to both ports to see if it would connect and it didn't. I called Audi and I was told that iPhone 5 does not connect in any way at all. If that's the case then why didn't the 4s or the ipad connect? Could it possibly be a bad wire/connection? If not, is it worth it to get an older iPod touch just to use for the car and will that work? It seems kind of ridiculous that a ford fiesta connects wirelessly and a 3 year old German car won't connect at all. Any help would be great!

Using iPhone 4 as gps on road trip?

I'm driving from MN to FL, and plan on using my iPhone 4 as a gps (using the google maps app). The trip is long, over 24 hours, and I'm wondering if the phone could overheat? Also, would roaming charges incur? I have AT&T as a carrier.
