Us Carrier availability?

Anyone know if any US carriers will be offering the device? I'm with T-Mobile and they have the Xperia Z (a million years after is initial release) and I was wondering if they may follow up with xperia z ultra?

No such information yet.
In fact, I hope that the Ultra WON'T be picked up by a US carrier since it will result in a branded, bloated version with outdated ROM and locked bootloader. The T-Mobile Z is a warning (stuck on 4.1.2 for now, ugly logo on the back, bloatware and locked bootloader) and I would be sad if such a magnificent device as the Ultra would be castrated and humiliated like that.
The Ultra should be experienced as a pure Sony experience. To paraphrase an old Panasonic ad: "Visit Sony Store. Sony all the way. Nothing else."
What I hope for is that Sony will sell the C6806 in their stores since the Sony Store is great. They offer decent financing options too with their Sony Card with different rewards and points for those that doesn't want to pay it outright.
It is time for people in the US to buy devices unlocked, unbranded, bypassing the carriers altogether. What those carriers are doing to their devices is just horrible and sad.

I have the unlocked, unbranded X.Z.U. running T-Mobile and I couldn't be happier!
The only thing is I have to turn off WiFi in order to send picture texts. Why? No one knows!
Look into your MMS settings, that might be your problem.

[Q] Buying NTT DOCOMO Xperia Z2 SO-03F

Hi guys.
I'm thinking about buying the Docomo xperia z2, I'm currently living in Japan and the z2 is definitely my ideal phone.
However, the launcher is a launcher specific to Japan, and I'm not exactly a big fan of it.
Does anyone know if it is possible to change it to the stock Sony launcher without root? I will probably root it, but just for warranty purposes I'm not sure if I will or not.
Also, does anyone know if the bootloader is unlockable on this model?
Any other general advice about buying a phone in Japan would be great as well.
Also would roms for the D6503 work for this model?
Thanks in advance for any help!

Launcher can be changed just by installing an APK.
Go to DOCOMO store and open up the phone and type in *#*#7378423#*#* and check if the bootloader can be unlocked.
Phone should be locked to DOCOMO, you need to pay a small fee to get it unlocked. You need to make at least one call on an active DOCOMO SIM to complete the SIM unlock.
I don't think D6503 will work, it may depending on the hardware. The SO-03F has a 1Seg tuner inside and may have different radio to access the docomo Xi LTE network.

docomo Xperia Z2 (SO-03F) has stock Xperia Launcher.
You can change docomo original launcher and stock Xperia launcher as you like.
but All Japanese Xperia models can't unlock bootloader, Japanese Career Model is locked bootloder.
You can flash D6503 Roms on docomo SO-03F, but some feathers are disabled.
In the case of Xperia Z, SO-02E rom can be flashed on C6602 and C6603. I think it should work on the other way around. Xperia Z2 should be the same way as well. The only concern is that you will absolutely lose oneseg/fullseg tv and mobile payment. I think the only main concern on Docomo Xperia is not the launcher but the annoying phonebook and dialer.
To be honest, even I'm using Xperia Z2 but when I went to Tsukumo and spent some times with SH-04F, I liked it more. It has better audio output via headphone, Bigger screen but not so big. My only concern is that I don't live there, I was just a tourist so updating device could be a real pain.

From my understanding the only real difference was the 16GB vs the 32GB of internal storage. But there is a place in Shibuya that said they would be selling it unlocked real soon called Mobile Japan..

Did you hear that in docomo shop in Shibuya?
If Sony Mobile Japan plans to release unlocked SO-03F, I'll wait for it!

Question before ordering a Z2

Hey all, I am very interested in this phone, but I have a question...
I had the Z1s on T-Mobile, and as far as I remember, it wasn't rootable, and I couldn't put my custom rom on there. Is this possible with the Z2? I would love to have a stock Google rom on there if possible, as I am not a fan of the Sony skin and bloatware, but I am loving the phone design, and camera.
Just make sure you buy one with an unlockable bootloader (not carrier branded) and root is no problem
I was planning on ordering through Amazon, I believe it says it is unlocked.
http://www.amazon.com/Sony-FACTORY-...qid=1401772900&sr=8-2&keywords=sony+xperia+z2
Will that work on T-Mobile?
Yes - I'm using it on tmobile. It gets LTE.

I'm also looking at getting a Z2 to use on T-Mobile in the US. I hope this unit you linked to is bootloader unlockable. Is this the lowest price you have found? I'm searching high and low for the best price before pulling the trigger.
Thats the best price that I've found online.
