In the US when you buy an iphone do they give a sim also along?

Like on the apple website I saw that the price of the iphone is far less than in my country but then I got to know that you can only use it with some networks… But I have a way to get it factory unlocked… Coz there are like many ppl in my country who do such things… So now my problem is that I'm not going to the US I'm getting it from someone… Someone elce is getting it for me… So now as they say that it is bounded to some network so you also would have to give your details to get a sim… But he would be a outsider(like the person whose getting me the iphone fom the us) so can he buy it… What all details he needs to give and… What al to do?

How many GB's do I need on my iPhone?

Hi, I'm finally eligible to upgrade my phone and I'm going to get either an iPhone 4s or 5 but I have no idea how many GB's to get!
My friend only has 8GB and she has to have a separate iPod to put her music on, but I'd prefer to just have it all on my phone to be honest.
I have about 700-800 songs, and I'd also have quite a few apps on my phone, so do you think it would be better to get 16GB or 32GB?
Also, any opinions about whether I should get the iPhone 4s or 5 would be appreciated!
