The Apple iPhone is quite a remarkable device. However, it is indeed a phone, so the simple functions (making calls, text messages, etc.) are standard and free(excluding the cost of the phone service). Also, if you buy the phone from AT&T you will be forced to buy a $30 monthly data plan, which will allow you to use the features that connect to the internet, such as GPS, web browser, and other things. The iPhone is also an ipod, so the music player is free, too. The actual iPhone comes with a small sock case, a wall charger, USB connector (allows you to connect to your computer), and a set of headphones (I may be forgetting something but that's pretty much it). Now its time to talk about apps. The app store on itunes has both free and paid apps. Apps can range from free to $100 dollars, but most cost less than a few dollars. However many of them are free and the paid ones usually offer "lite" versions; a free demo basically. And as long as you get the apps from the app store on itunes, they should always work.
