T-Mobile Xperia Z3 (D6616) - Future Development and Support - Marshmallow, WiFI LTE handoff, etc

[s1dest3p]

Sony Mobile announces that the Z3 will get Android Marshmallow, but yet T-Mobile is not aware and the support page for the T-Mobile Z3 (http://support.sonymobile.com/us/xperiaz3tmobile/software/) doesn't reflect such like the regular Z3 does (http://support.sonymobile.com/us/xperiaz3/software/). This is very concerning to us Sony and T-Mobile customers that spent a lot of money on a great phone; we're worried we're being forgotten or left out. Maybe sales weren't high for the T-Mobile Z3, but what about us that were loyal to Sony and spent hundreds of dollars on the Z3 - don't we deserve the latest and greatest updates, like Marshmallow, Concept for Android, WiFi Calling to LTE hand-off, etc?

Please give us some reassurance that you are still committed to your T-Mobile customer base and that we'll be receiving Marshmallow and possibly other updates I mentioned above around the same time that the regular Z3 is.

I'd really appreciate your response and hopefully confirmation. Thank you in advance.

This is on Sony website:

My Android™ Information

The availability of wireless software updates depends on your country and/or operator.

No new Android™ version is currently planned for Xperia™ Z3 T-Mobile

Android™ 5.0 Lollipop is released for Xperia™ Z3 T-Mobile

That pretty much sums it up ...so now someone needs to be able to jailbreak this 32 GB phone so we can update it past Lollipop

Thanks to both Sony and T-mobile for making this an unpleasant experience.

It's not going to happen. Both T-Mobile and Sony abandoned the D6616 the day T-Mobile dropped it from its lineup.  The T-Mobile tech forum was like 20 pages long full of vitriol. 

Remember the Z3 is nearly 6 years old. The locked bootloader on the D6616 prevents jailbreaking the device for new Mods
