Ok, so I recently switched from Verizon Wireless using the Treo 700W to T-Mobile using the Blackberry 8820 with WiFi. When using the Treo 700w, I used a wireless card in the slot to access my wireless internet at home without using any cell phone minutes. It was a completely separate function and I liked it. I'm new to Blackberry but I wanted to give it a try. I have wi-fi at home and I am able to set up a connection and my wi-fi is dark/black. When I open the "browser", UMA words are at the top and if I try to navigate to a website, I get a message from T-Mobile that wants me to subscribe to unlimited web access for $5.99 a month. So, am I actually accessing my home wi-fi to access the internet or am I just using T-mobile's edge network? I are confused! Thanks for any explanation you can provide.
