Does an iPhone NEED a service?

Can an iPhone work without an activation with a service because I just want apps on my iPhone and not call anyone or waste my money on at&t because I want to use it as an iPod touch but iPod touches like the 5th one aren't so awesome for me so I just want the camera and apps on the iPhone without a dumb service to pay money for calling which I don't need to do

No it does not you just need Wi-Fi to connect

WHEN IT DIES., IT DO,. UND A PROPER GRAVESIDE ONE.

No, I don't think so.
