iPhone to iPhone communication

I have been looking into communication methods between two iPhone devices and as I understand it there are two main methods to do this: Bluetooth and WiFi. However I wanted to know if anyone knows of any other way of sharing information between two iPhones? If I were in an area with no Wi开发者_运维技巧Fi or mobile signal, and couldn't use Bluetooth for whatever reason, is there anything that could be done to broadcast data from one iPhone to another?

I'm sure its a bit of a silly question, but if you don't ask, you don't get; and if someone knows of anything I might be able to look into with regards to this, I would be very appreciative.

Thanks,

Dan

AFAIK Wifi and Bluetooth are your only options for direct phone-to-phone communication.

Offcourse, there is still cellular data network because you are talking about the iPhone ;)
