has anyone though of making a mod from a smartphone? I just upgraded to the galaxy S4 since my mic on my S3 don't work. The S3 has a 3.8V Li-ion 2100 mAh battery. I think it would be cool to have a app that controlled the VV/VW functions and make a headphone jack to 510 connection adapter sine the headphone jack is on top. I think this would be a cool mod.
