You can buy an iphone without the plan straight from Apple for about 400 USD, if you're not willing to pay that price you can check eBay or Craigslist. You might find a better deal depending on the generation or condition of the iPhone.
Yes
The iPhone has to have a data plan because of all the cool features so you have to pay the $30.00 fee every month. I do not think they charge you to switch from a regular phone to an iPhone. I know they will not sell you one if you do not buy the data plan but it is pretty expensive so... I guess that is why they charge. The data plan is important.
yes. eBay.
No, you have to get the Internet package.
The iPhone has its own Service Plan which has Internet included.
You can use the AT&T iPhone coupon code if you plan to purchase an iPhone. You can not use it if you plan to buy another phone.
No, because it is associated with APPLE you must but the whole plan because the phone will not work with the prepaid chip.
No, because it is not a cell phone, but an mp3 player. An iPhone requires a plan if you wish to call and text.

Try Ebay or if you want a plan with it, AT&T's selling some for $99.
Yes, but you have to buy it at full price which is very expensive!
