[Q] Does Xperia Z1 have unlockable bootloader?

I've been looking if Z1 has bootloader locked or not but searches are turning up blank, so I thought I would ask here.
Other question is will unlocked (carrier) Z1 support T-Mobile USA LTE? Going through http://www.gsmarc.com/sony/xperia-z1/reviews/ and http://support.t-mobile.com/docs/DOC-5627 seems that Z1 won't have any problem supporting any LTE currently available, even then I want to confirm before I place pre-order for unlocked device
Thanks

Bump.
Does nobody know or is it too obvious and I still missed it? Or the information is not yet available?

[Q] D6633 vs D6643 (firmware-wise)

Ok, first things first!
I actually don't really like dual-sim but since my Z1 got bad and I had to swicht back to S3 (HUUUUGGEEEE downgrade) a dual sim Z3 will be amazing, but I have some concerns...
I have some kind of predjudice against dual sim phones, but, since there are no unlocked D6643 being sold in my country, I just ordered a D6633.
That being said, I used to have a Z1 C6943 model and could flash C6903 firware version without any hickups, losing only tv, wich didn't matter at all!
My main question is: Will I be able to flash D6643 firmwares on D6633? If this is possible, what would be lost?
Thaks a lot guys, I still have 11 days untill my phone arrives and untill then I can cancel the purchase!

If there is a difference in partition tables, it might not be a good idea to try. I encountered such issues when flashing Korean Stock ROM on my LG Nitro. Though hardware was compatible I had issues like no cellular and almost bricked attempting to flash back to ATT stock ROM.

[Completed] Is it okay to use Sony Xperia Z3 (SOL26-Unlocked) in India?

Hello! I need to know whether should I buy Sony Xperia Z3 (SOL-26) or not.
I'm having 2 options with SOL26-Unlocked & D6603 of Xperia Z3 models but I'm confused as SOL26 is mentioned to be a Japanese version but in lesser price compared to D6603.
As I want to use this phone in India, is Japanese version okay to have?
Which one should I get so that I won't be having any problems regarding network bands in India or custom ROMs or other issues.
Please help!
Thank you.

Hello, thanks for using XDA Assist.
An official Indian thread for the Z3 is available here, that would be the best place to start browsing what variants others are using.
The best place to ask would be in the Q&A,Help section for the Z3.
Good luck.
