    Ive been reading many threads, but havent found a definate answer.

    If i purchase a T-mobile 9900 and install the leaked 7.1.0.205 os, will WiFi calling work?

    I dont care about hotspot or nfc, etc.

    If 7.1.0.205 does NOT enable wifi calling is there a Leaked/official os that does enable this feature?

    thank you!

    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
