Is the iphone 5 unlocked when brand new?

Hi

I'm thinking of getting an iPhone 5 brand new from mobiles direct but it comes with a pay monthly vodafone data plan.

If i don't insert the vodafone sim at first use but enter my t mobile pay monthly sim will it then become locked to t mobile or is it locked to vodafone from factory? Therefore its already locked to vodafone before entering sim at first use.

I would ideally like to use the vodafone sim in another phone and use my t mobile sim in the new iPhone 5.

Any experience on the matter would be appreciated.

Why doesn't my iPhone 4S have FaceTime in the settings, can't use?

Had my iPhone 4S replaced due to a cracked screen about a month ago. Since I replaced it I have not had iMessages or FaceTime, tried to turn it on and play with settings within my Settings but there's not FaceTime setting available. I know it should be there but is here any reason it wouldn't be? And what can I do to fix it besides a trip to the apple store?

How to get a sim card for an iphone?

My iPhone 5 Screen Broke. What Do I Do?

^This it what it looks like. The phone still works and I can still listen to music with it. It still charged and everything but the screen is messed up with this fuzzy, scanline thing.

I've never dropped it, damaged it, got water on it, or anything that could have messed up the screen.

I randomly started to get scanlines on the bottom of the screen and just yesterday the entire screen is messed up so I can't access anything on my phone.

I bought my phone this past May, and I don't have insurance because it costs too much for my family to pay for.

If I bring it to the AT&T or Apple store, will they replace it for free? This is obviously a defect because I haven't done anything to cause this.
