I've been looking into it, and found FSK a suitable solution. I have a few links you could check out (most involve the Arduino, but you can ignore that).

• http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1274970878 (blog post on arduino forums that is helpful)

• http://translate.google.com/translate?hl=en&sl=ja&tl=en&u=http%3A%2F%2Fjp.blog.reinforce-lab.com%2F (japanese description of FSK from iPhone to Arduino)

• http://code.google.com/p/arms22/downloads/list (software libraries)

• http://sree.cc/electronics/arduino-as-an-fsk-modem

• http://www.perceptdev.com/labs/iphonehacks (old iphone hack that creates a FSK modem with the iPhone)

• http://www.progical.com/ (company that sells such dongles, but wouldn't reply to me)

• http://eecs.umich.edu/%7Eprabal/projects/hijack/ (awesome project)

If you really want a realiable solution, look into serial data (jailbreaking might be required, but awesome for prototyping):

UPDATE: Thinking outside of the box, if you want a really reliable solution; I bought this recently. http://redpark.com/c2db9.html
