[shahid200]

Hi Guys
Just want to know if anyone know how to use or setup tethering using Android Phone, I have free Add-on for Tethering, I setup my phone as Modem using PDANET software for tethering but every time I use net it uses my mobile internet data not the 3GB tethering, I also try EasyTether Software and also tried using Internet Sharing option available in phone but same any idea any one.
