Is iphone 5 kind of a downgrade?

I saw the iphone 5, the lenght and weight doesn't impress me, it feels like a plastic toy, iphone 4s is way better, looks better, feel better (if they update it what the iphone 5 features has it will be much better) well thats my opinion. It might have good features but does it feel right for you? Does it look nice? Seems like its easy to break. The charger port is kind of stupid, how am i suppose to find a charger at friends house if they don't have an iphone 5! They are trying kill all the iphone generations and start with this piece of shyt.

What service provider is iPhone when bought in Apple store in US?

What service provider is iPhone when bought in Apple store in US?

When someone buys an iPhone from Apple in the US, is it locked to a certain mobile service provider such as AT&T or is it unlocked for any service provider?

I have a relative going to US from the UK and so there would be no point in buying an iPhone there if they are locked.

Thanks

Added (1). I have just had a look on the Apple US website (i'm from UK), and when you go to select for instance an iPhone 5, apple then directs you to select a Carrier such as AT&T etc. How would I get an unlocked iPhone 5? And where would I get it (apple store, or apple online).

Added (2). There are two comments below this -

The first saying that there are unlocked iPhone 5's on the Apple store US,
The second saying that the only unlocked iPhone 5's is on the Apple store UK.
