Yes you can do all that I'm pretty sure I'm positive it has all that actually or it wouldn't be an iPhone if it didn't
Yes, you have to have an iPhone to download iTunes to a phone
The phone must be apple(e.g. iPhone) and iTunes on your iPhone will be updated every time you plug it into your computer that you use for iTunes.
activate the phone first and then sync it with your itunes on your computer
if it is an iPhone, iPhone 3G or 3GS
The Iphone and the Ipod touch are almost the same thing except: -The Iphone Has a camera and GPS - Iphone is an ipod touch with the phone practiclly theres your answer!
sync you Iphone with your Itunes library.
The only phone that can run iTunes is the iPhone. iPhones lack the capacity to burn.
if you can access itunes on your phone you can download music through there ,but if not you can use itunes on your computer , download them through there and synchronise your iphone with your computer.
the IPhone 6
No, iPhone ringtone file is .m4r extension
There is no iPad phone. I am assuming you are talking about the iPhone and the iPad cameras. The iPhone camera is currently on the same level as quality as the iPad camera.
You can restore the Phone in iTunes!Restore the Phone in iTunes!
