I am trying to wirelessly program Arduino Fio using XBee-PRO® 802.15.4 with embedded antenna.
I searched the following methods:

http://www.ladyada.net/make/xbee/arduino.html
http://www.sparkfun.com/tutorials/122#Step1
It seems the 1st method is the simplest one. I tried it but couldn't make it work. My questions are:
Is the first method the right method to try?
In the Step 4 of the first method, I should click on the button for Upload right after the print output "Arduino will reset in 5 seconds" and before the print output "Resetting NOW", is it right?
Also, I used a 2N3904 transistor instead of the required 2N2222A transistor in the first method. The result is the 2N3904 transistor could not pull the Arduino reset pin to ground.
Anyone with the 1st method or experience in wireless arduino programming can help? Thank you!
