The best place to buy accessories for the IPhone is AT&T because they sell the IPhone there. You can find them a lot cheaper on EBay, but they may be not from Apple.
From apple.com, At&t stores, best buy stores, and eBay.
If you mean just the phone and not the AT&T service then yes. When you buy the phone from AT&T they give you the phone and you activate it through iTunes. You can also buy the phone from apple. In a store or online.

There are many retailers that one can buy a laptop from that is compatible with an iPhone, however, Best Buy and the Apple Store may be the most popular. Best Buy because it specializes in electronics, and the Apple store because they make the product.
