Hi and welcome.
What is the make and model of your phone? You could only connect it if the phone has wifi capabilites.
if your phone has wifi capabilities then follow this http://community.bt.com/t5/BB-Out-About/any-news-on-voip-for-touch2-hero/m-p/12877#M1192
I have set up my desire without any problem
My phone is a LG GT405. I do have internet access via my 3 contract, but wondered if I could also utilise my bt hub as the signal strength where I live via my phone is hopeless!
you need wifi acces not 3g and don't think your phone has wifi
