I have had my BB 8220 for a couple of months now through Tmobile and I have not had any luck connecting to the internet over Wifi. Each time I try to connect it either times out or tells me that I need to sign up for a paid data plan. I have asked the people where I bought the phone and they have no idea. So here is what I have tried so far. I have gone into advanced options, browser, and change the settings to hotspot browser and it does the same thing. I even tried it on the regular browser and the WAP browser but no difference. I even tried on my home wifi which is a linksys-G and it still tells me to sign up for a web-2-go program. I don't need to use the internet much but when I do it sucks to get nothing up an upsell from Tmobile.
Any thoughts?

Somewhere I rememeber reading that you need a bb plan for Wifi access, but can't recall. I did find this though and maybe it will help.

Did you select the correct browser? Be sure to select the hotspot instead of the tzones/web2go.
