Iphone 4 aux + microphone

[6moe66]

Hey folks,

Thought i'd put the shout out and see if anyone on here has tried to get their Iphone 4 working like a hands free through the aux.

Problem is...... I've just upgraded from a Nokia N96 to a shiny new Iphone 4 and the beauty of the Nokia was that it came with a controller which plugged into the top of the phone with two separate 3.5mmconnections - one from the phone to the controls(play, forward, etc...) and the other from the controls to headphones which i ran to the aux in car via a standard male to male 3.5mm cable. It also had a microphone which allowed me to speak and use the aux hands free.(strongly advise anyone without a hands-free kit and a N Series phone to do this)

So, I want to do the same thing with my Iphone but i'm new to the Apple kit and know they have a reputation for changing compatibilities on their new stuff, just so you have to buy the corresponding equipment. I've found this below and thought it would be worth a shot;

Has anyone done something similar with an older Iphone and does anyone know of compatibility issues with microphones/stereo out of the Iphone?

Should really be posting this on an Apple forum (which i will) but thought it would be worth raising as i think it would be beneficial to all.

Cheers in advance,
