1) Blackberry 8320 with no Blackberry plan connected to wifi, we know that you can surf and do emails over wifi, what happens if you subscrible to T-Mobile@Home (UMA) plan, now you have wifi icon on the screen and UMA icon on the screen, I know that the voice calls will now go through UMA but what about data, will I be forced to use data over UMA (from the mobile provider) or will I be still using my local wifi and my own ISP for internet access and emails?
