I finally got a T-Mobile Wing so I can use TTN6 properly with a touchscreen. I was previously using the software installed on a T-Mobile Dash and I operated the software using SPHelper. However, after some comparison, I notice that I can't use the "Call Number" feature when I use the smartphone (Dash). The feature works fine via the T-Mobile Wing. I can access the feature and find numbers to POIs but I can't call it because I get the "unable to call, no dial tone" message. Does anyone have any insight on this?
