Today cell phones NEED this type of stuff from the get go!
So, hang on...do I understand you correctly? You want the BlackBerry company to control the TMobile company? For, you see, to accomplish what you have stated, such would be required.
Each carrier is responsible for the rollout of their UMA services, if they even have them. BlackBerry cannot control a carriers UMA service availability...the carrier must control that. So, to do what you stated and since BlackBerry cannot control TMO, BlackBerry would have had to delay the rollout of this fantastic new device while waiting for those few carriers that even have UMA to make it ready and available for the BB10 platform.
An interesting consideration, to be sure...but they must make their choices when they must make them...and so it's TMO that has the brunt of the "blame" here...not BlackBerry as far as I can tell...
What's making it hard for me is that my 2 Z10 device purchase(1 for wife) is being threatened by Tmo offering the PHAT iP5. Does that phone have wifi(UMA) calling?
As for your last question there...it seems that a BlackBerry forum is not a good place to ask that, since it pertains to a different manufacturer's device...

Since UMA requires hardware you won't see it anymore. T-Mo has used Kineto on previous phones and now IMS -- both can be added OTA. Which is the whole point. There is apparently a Beta version for Windows Phones out there now. My wife has the original UMA on her older BBerry and hand-off works just fine.

This is the question I want answered before I upgrade. It took ages to get the sofware update for the 9900 Bold, so until the UMA is activated I will not be upgrading, I need it as no signal where I live.

the major difference between UMA (Unlicensed Mobile Access) and WiFi Calling is that UMA uses a UNC (UMA network controller and wifi calling does not. the UNC is what enables GSM handoff.
The first thing a UMA enabled handset does when entering range of a Wi-Fi network is attempt to connect to that network’s Wireless Router (WR) in order to get internet access. Once connected to the internet, the handset sets up a secure tunnel all the way to the provider's network (the Security Gateway). If the subscriber is authenticated and authorized for UMA service, the handset is connected to the provider's network, via the UMA Network Controller or UNC and is ready to provide service to the subscriber.
WiFi calling uses only a VoIP connection type without creating a virtual GSM connection between the cellular network and the VoIP network and this is why UMA has handoff capability and WiFi calling does not

The last version of BBerry that got wifi calling (as an OTA) was the IMS version, not UMA. According to what I've read. My wife's 9xxx BBerry uses "real" UMA and has no issue with hand-off, and we've had 3G in So. Cal for years. Prior to IMS, T-mo used Kineto, which was another software-only that could be added, and was added OTA to many Android sets. When Z10 gets wifi-calling it is 90% sure to be IMS, and 90% sure there will be no hand-off. But, maybe. Neither IMS nor Kineto needed hardware on the phone and neither allowed hand-off.
