Wireless connection between arduino and smartphone

Hey this is my first post here.

I was wondering what components i would need to make a wireless connection between a arduino UNO and an android or apple phone? I need to send data from the phone to the arduino within a max range of say 3 meters. I am assuming bluetooth would be my best bet? Thanks in advance!

Sorry for the delayed response, but for anyone else searching:

Yup, bluetooth is going to be the easiest option. The Bluetooth Mate boards are really user friendly and easy to get started with.
