All things pertaining to wireless and RF links

I want to use my iPhone to send a message wirelessly to an arduino. I guess I could use BLE or wireless. I want to do this out and about so I won't have a wireless router.

I'm pretty familiar with C/C++ but not java or anything like it. I'd like to use Sparkfun gear if possible, any suggestions on the easiest and cheapest way to achieve this?

I'll be close to the Arduino with my cell phone. (10 feet or less). I'm assuming cell phone coverage as I am in the USA. I would not think it was safe to assume ao open wifi connection as this is a mobile (in vehicle) application.
