Why does my New Iphone say 3g at the top?

I bought a 4s today, with a two year sprint contract. It says 3g up at the top?
I was reading that the iphone 4s is not actually a 4g phone. Is this true?
If that's the case, should I return my Iphone and get the samsung galaxy 3s? (I was debating between the two, but I like the Iphone's usuability and I THOUGHT they were basically up to the same performance level. Since the Iphone was on sale, I decided to go with it. But, I can still return it and get the other at no return charges, since I just bought it today.
Also, siri is slow, and telling me she can't answer or just not responding. Plus the network is super slow.

Should i buy the new iPhone 5 now, or wait for my contract to expire?

I have an iPhone 3GS and my contract expires in March. I'm thinking of adding a new line and getting the iPhone 5 on that, and then cancel my iPhone 3GS's line in March. My carrier is AT&T. How much would it cost to have the additional line on my account for the next 5 months? I'm also INCREDIBLY impatient if thats a factor haha.

Will Sprint Unlock My iPhone if I'm Traveling Internationally?

I'm going to Philippines with my friend in two months and I was wondering if Sprint would unlock our iPhones.
If they will, would it be free? Cause I plan on using it in Philippines. We're just going to buy a sim card.
When I was with T-Mobile, they unlocked my phone for China.

How to add songs from Itunes to Iphone?

When I try to add these songs, they are in the music area, so i try to autofill from music. It adds some artist but not all. Out of 3 albums for one artist it only added 2 tracks. When I try to just add the artist it won't let, it says they are already in my iphone so they can't be transferred. They are not in there! Hence i'm trying to add them! Lol
