Hi,

I hope i can answer your question here.

I bought my N900 3 weeks back. Last week I asked T-mobile USA to enable web2go unlimited ( $24.99 pm) and everything started working in couple of hours after i have restarted my mobile.

Initially i was unable to configure yahoo mail on my mobile ( Make sure you select yahoo mail and not yahoo mail plus). But after few days i have deleted that and re created new one it started working.

Hope this might be helpful.

Regards,

RR
