I tried to look for that on the net but there are so many different things they say. I had an ipod touch 2g mb model,which I finally gave to my gf when i bought an ipt3g, coming with an earphone equipped with mic working perfectly. When I tested the earphones on the ipt 2g, the mic did not work. I then bought a cheap $1 earphone on ebay which specify it 'should' work with ipt2g, the phones worked but not the mic. Though I doubt the quality of the $1 earphone,I'm asking myself if the 2g isn't faulty. Does anyone who already used a mic on the ipt 2g help me plz.
