Does an iPhone restore from backup move the phone number?

I recently moved to the iPhone 5(and switched numbers), but I need information from an iTunes backup of my old iPhone 4.

If I temporarily restore from the old backup, grab the info, and re-restore it to what it is now, will my phone go back to the old number or keep my current for that small amount of time? I realize normally phone numbers carry with the SIM card, but I'd rather ask and know for sure.

Also, both phones were running the newest iOS 6.0 so I will not be switching between OS's - if that even matters…

Somebody I know just lost her iPhone 4s - what should she do?

She called me on her friends phone obviously.

i tried to call her back but obviously she's using that phone of her friends so its engaged.

i simply wanted to tell her to call her wireless carrier and tell them to cut the service off that phone cos if its stolen and in the wrong hands - that individual could rack up insane charges etc

what's the FIRST thing she should do? Report it stolen to the police?

Sending picture message with Iphone?

Quick question everyone. Would it be possible to send a picture message to everyone with the same beginning letter in their last name? The reason I ask is because my girlfriend has a guy friend that sent her a naked picture and afterwards sent a text saying, "if you got this, please delete it. The picture was sent to everyone in my contact list with a last name beginning with C". I think he did it on purpose and used that as an excuse because I can't see how that's even possible.

How to restore my iPhone to remove jailbreak and then unlock it?

I want to remove the jailbreak from my iPhone by restoring it however it isn't unlocked to 3 so if I do it, it will ask for a sim which I don't have. Is there a way to restore it then unlock it to 3 without jailbreaking it?
It is a iPhone 3GS by the way.

Added (1). Ffs just went on my phone and its stuck on the apple boot logo, the power button don't work so i can't turn it on or off and its not being recognised by itunes!

Iphone car remote start plan?

So I want to get my Girlfriend a remote start/keyless entry/ panic alarm system for her car, and she recently got a new Iphone. I searched that they can install everything but it costs extra with your cell plan to have the app to do all this from your Iphone. I'm just wondering roughly how much the plan costs monthly to maintain it?

IPhone 4S/5 videos are blurry when sent through mms and email, why?

My frend took some fan cams at a concert and when she sent them through text they came out extremely blurry. She sent them through email but it still came out really blurry, so blurry you can't see the faces of the band members. Is there a reason why? She has an iPhone 5 and I have an iPhone 4S. I can't send my fan cams to her, through email, either, the file is too big. Is there a solution or am I *** outta luck?

Which iPhone 4s case should I use?

I drop my phone more often than I would like, so I'm looking for a good, protective iPhone case. However, I'm not a big fan of really bulky cases like the Otterbox Defender Series or the Otterbox Commuter Series. I've considered Switcheasy CapsuleRebelX and Odyssey, but I don't really like the designs. Right now, I'm debating over the following cases:
ifrogz Cocoon
Speck CandyShell Satin
Speck CandyShell Grip
Cygnett Apollo Hybrid

Any votes or further suggestions is appreciated.
