After an upgrade to( v7.0.0.250/Platform 5.0.0.448), still no WiFi or UMA calling
I'm patiently waiting
BTW: The upgrade has improved the battery time, & also maximized my Bluetooth Acura TL 2012 SH/AWD functions immensely
If only TMo would put out the software upgrade for the WiFi calling.................
FYI: I had to upgrade & run application loader, due to error message 517
TMo actually sent me a link to do it in 35 minutes, through Windows Vista
