Would this work?
Seeing as a cellphone headset is 2.5mm, and an xbox is 3.5mm, could you use a converter to use with VoIP? :o
Like THIS. (http://www.amazon.com/gp/product/B0002ZPFAS/ref=pd_cp_e_2?pf_rd_p=250314601&pf_rd_s=center-41&pf_rd_t=201&pf_rd_i=B0002ZPF6W&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=033F5EW7B8249FED3E85)

no, the pins on the headphone jack are "inactive". You can only use a dock connector mic.

Ah, upsetting. Thought i had a breakthrough.

you could create a mic but instead of a mic on the end, it is a connector to plug headsets etc. in.

i'm gonna buy one from family dollar. :Z
