    On Tuesday I called T-Mobile to upgrade from the 9700 - 9900. They looked an my current plan which has $9.95 for UMA calling. We completed the order and I received the phone today. Charged it and went through the setup. No UMA. Called TMO and was told that the 9900 does not support WiFi calling and they do not have a date when the software update will be released. I called them back to get an RGA and get everything back to the way it was 3 days ago. First person told me they can't cancel the contract since I accepted the terms. It took me 3 different people to get someone who could comprehend the situation.

    Lesson learned - Don't do anything before doing your homework here on CB.

    There is a leaked OS, 7.1, that supports wifi calling and wifi hotspot....You may want to try this...

    I suppose,you have the stock TMO OS, which is 7.0...250.

    You failed your homework.

    The 9900 does support wifi calling, and a beta version of the software has already leaked... http://forums.crackberry.com/showthread.php?t=673031

    There are plenty of working mirrors in that thread if you search for them.

    One that definitely works is here... RROYY - LEAKED OS

    I've used leaked versions on other devices before with minimal problems if any.
