Well, I went to check out the T-Mobile branded Xperia Z C6606 at the Sony Style store and was disappointed to see that the bootloader is locked.

I was trying to get information online if it was locked or not but couldn'tget any confirmation. I know that it'sprobably locked by T-mobile, but I was hoping.

I've seen some phones in the past that were sold by T-Mobile or other carriers but were not bootloader locked. With T-Mobile's new business model and the fact that Sony was selling it outright at their stores, you would think that it should be unlocked.

All phones have locked bootloaders when they come from the store. 'Bootloader unlock allowed' means if it is allowed to unlock it yourself or not, but doing so will void your warranty and wipe your DRM keys (which are needed for Mobile BRAVIA Engine 2, MusicID/Gracenote, etc.).

There is a carrier here in Spain that sells unlockable Xperias. It's the fourth mayor carrier so is not a shady one.

sim locked and locked bootloader are two separate things. >.>

usually when some stores states "selling unlocked xperia/galaxy/iphone/ etc.." it means the phone is unlocked and it can be used anywhere else. When you purchase a phone from a store (Sony store) or carrier (At&T) it is locked to them. In other words, the phone cannot be used with another sim card like T-Mobile, since the phone is locked to At&t.

I totally understand what is sim and boot lock.

I've had in my hands a couple of Xperia devices from that company (Yoigo), one Xperia Mini Pro I think, and the other one a Xperia Z, and both had "Bootloader Unlockable: Yes" on the service menu.

I've read that some custom ROMs can still be flashed on this phone without unlocking the bootloader. Is this true?

Yes, if they are based on the stock kernel.

T-Mobile isn't really known for locking bootloaders. Verizon on the other hand... When it comes to locked boot loaders it seems to be like this.


Locked carriers:
Verizon
at&t

Mostly unlocked carriers:
Sprint
T-Mobile

Phone brands locked:
HTC
Sony Xperia
sometimes LG

Phone brands not locked
Huawei
Samsung

This has just been my experience.
