Communicate

I may be asking the wrong question but I am a noob in this situation. I have hardwired a switch (analog input) to the Arduino BT and am using the website's example code to count the number of switch depresses. I then want to send this count to a cellphone that will display the number on screen and possibly perform a phone function based on the range of the count, such as dial a number. My primary question is what format is the data sent from the Arduino BT to the cellular phone and how do I go about programming the phone to read the data? I already have written a program for the phone that uses the phone keypad to input data in order to perform a certain action. If you wish to direct me to another thread, that will be helpful as well. Thanks for any help.

What mobile phone are you connecting this to?
