Just got a new iPhone 4, messages are being sent from email?

I broke my phone so I was sent a new one. After setting it up all of my messages are being sent from my icloud email. When I go into settings and go to iMessage there's an option to change where I would like to send and receive messages. The only option I can choose is my email. There's an option for my number but it is grayed out and I can't chose it. How do I fix this?

How to transfer photos and videos from my iPhone 4S to my Windows Vista PC?

With my old 3GS, I used to just plug it in with a USB cable and a dialogue box would open on my PC to see if I wanted to 'Import Pictures with Windows'. This used to import all photos and videos on my iPhone. Then I got a 4S and this still happened, but it would only import the photos, not the videos. Now I'm not even getting the dialogue box. How do I transfer my files please?

Can you use an iPhone with a USA sim card abroad?

SO I found two pretty cheap iphone 5's on ebay. One is locked to Sprint and the other is locked to AT&AT… Now in the AT&AT one there's the sim card verification error.

If I were to buy a Nano Sim for Activation Screen Bypass Only would I be able to freely use my iPhone in Ireland?(I'm not interested in making calls and texts for now I would just like to try the phone out)

Oh and also could anyone explain what this means? I'm not very techy:
FOR PARTS ONLY - AS IS

ABSOLUTELY NO RETURNS.

WON't RESTORE WITH ITUNES.

Please VIEW ACTUAL PICTURES.

iCLOUD IS DISABLED AND THE ESN IS CLEAN. THE MOISTURE STICKERS ARE WHITE.

Anyway thanks… Please don't tell me to get an android phone or anything like that because I have one… Just answer my question please.

I asked my girlfriend on break where she was and she lied to me. She was in the pub?

I have a girlfriend of many years and we have a break now. We talk to eachother on daily basis. She had an revenge affair with some guy back in January but i forgave her and we became a couple again, but as I mentioned, were on a break at the moment.

Yesterday at midnight i tried to call her. She didn't answer the moment, But imidiately after she sent me an sms with the sentence "I can't answer the phone, my grandmother is here" (at her apartment). I Then tried to log in to her iCloud account as she uses the "Find-my-iPhone"-feature, and to my surprise I entered a correct pass which was a simple one. I then could se throguh gps that she wasn't at home at all, she was in the pub! I then confronted her saying that i knew she was in the pub and she started to suspect some gps hack. She first tried to say "no, i'm really at home" but after a short while she admited that she was in the pub as I described the pub name. She said she was gone out because of diversion from kids and that she was sitting home most of the time. And she also admited that she was drinking. She then said she was sorry for lying and she was about to go home. I started to ignore her from that time by not sending many sms and answering her calls. After she sent last message about 0230AM when pub closed she used 1hr 40mins to go home which is 5mins walk away & turned off gps. She was propably stadning outside pub area talking to guys. She hasn't sent me message since then.

How should I deal with this?

Things to do in the car / good apps for iphone?

So I'm going away for 1 night tomorrow (Monday) and I want to know some good things to keep a 12/13 year old occupied. I don't want to take loads of stuff in the car so is there any apps on the iPhone which are really entertaining?

Don't leave comments saying 'read a book' or 'talk to people' because 1. I can't read in the car as it makes me sick and 2. Isn't talking a bit obvious?

Best way to save battery life for iPhone 5c?

I know that after using your phone for awhile, the battery life decreases faster. But my phone's battery life goes down extremely fast. Whenever i turn on my cellular data, after like 10 minutes I would have already lost 8%. I'm very careful with my charging. I charge every night and wait for it to be 100% and then use it. I also let it die at least once a month too. My main concern here is about the cellular data. I see other have it on for a whole day without it wasting their battery life much.
