do you guyz think that there will be an exploit that will alllow this ? I came from Xperia 2012 and I don't heard about something like that, and on xperia 2011 if I remember correctly there's one with paid software se1tool something like that and test-point, so with the 2013 lineup there wouldn't be one ?

I got my X8 back from service 3 days ago.poor phone was hard bricked while trying to unlock bootloader.I might have done something wrong though because it seemed to have unlocked at a point, maybe not...Anyway i think it was 11W43.The one i have now is 11w03 but whatever it was i wouldn't try it again.2.3.7 is good already no need for ICS

He can try if he wants, BUT ( quote taken from b.jay's post of bootloader problem)
If the date code on the sticker reads 11W29, or any later date (11W30, 11W31, 11W32, 11W33, ...), DO NOT attempt to unlock the boot loader.

no, i didnt read properly earlier, i thought you said 11w29 but you actually said 11w02
Anyway, no, the risk is low, there will be 99.9 /100 % you can do it, the only thing that can screw it up now, is if something interrupts the process like anti-virus etc
I left my Antivirus on and it was fine

uhhh, ummm, if you were unlocked to any network (if that is what you mean) then you will return to being locked to original network
@Irishstuff09 some anti-virus can interupt (lol, i didnt turn mine off but worked for me too )
but sometimes, the programm can fool the antivirus (which is good in this case, but bad cuz it shows how s*it the anti-virus is and how it can bypass etc)

"Cannot" as in never? or is this something that may change in the future? Because I just received my phone in the mail today, and this locked bootloader is very disappointing. I might just return this phone if unlocking is not an attainable option for me.

check the service menu. It will tell you if it allows you to unlock it or not. Its always worth a bit of reasearch about this before laying out £350 or getting into a 2 year contract....

Just out of interest, when an FTF file becomes available, could you then flash it with flashtool on a stock ICS locked bootloader?
Judging by past firmware updates, it's taken 2/3 months for Orange to push an update.
Yes, or you could flash the 303 generic UK and ota to current. You'll then get jelly when Sony says not ee.

I wonder how I flashed my V with its locked bootloader to Xperia VL's firmware using Flashtool, then.
All you need is matching signatures, and all similar models share them.

Sorry but you've got that wrong, you can use flashtool to flash an official ftf onto a phone with a locked bootloader, I've done it loads of times with my xperia's. In essence if your locked to a network orange, t-mobile ect then you can get the region generic ftf and flash it with flashtool to debrand your phone
What you can't do is flash custom ROMs which require a custom kernel.

Thanks for the responses guys, I thought it would be possible, the only reason I ask is that I've flashed ICS firmwares to the T in the past, but wasn't sure with it being a different version of the OS.

Please read before continuing to facepalm yourself.
Flashtool does not require your bootloader to be unlocked. It also does not even you require your phone ot be rooted.
Flashtool can be used on any xperia phone regardless. It does not require fastboot

So this is 4.1? I got the update in sony bridge, but updating means I lose my root right? (locked bootloader)
Yes when you update to different firmware you will lost the root privilege

Not always, there are ways around it. But in general yes.
Once the new firmware hits users with locked bootloaders we will see if we lose root, but then we will also find a way to root the newfirmware or find a way to update that does not lose root.

[Q]Bootloader Unlock Allowed: No = forever stock Kernel?

Forget about unlocking the bootloader, its not possible. No over/under-clock for you, no CyanogenMod or other goodies.
All carrier branded phones are locked and almost impossible to unlock.

is there chance to have -Bootloader Unlock Allowed: No - when my phone is from shop ? ( not from carrier, not branded)
I think that it's not the matter of branded/not branded etc. beacuse I've seen bootloader unlock allowed: yes after I rooted and installed CWM and TWRP; today I've reverted rooting via SPC and the bootloader unlock allowed is back on: no; so I think someone has to look through it to see if you can override it...

I doubt the Sony bootloader will be cracked any time soon as the Xperia T was never cracked and thats a much older device.
Unfortunately that means no custom kernels/CyanogenMod.
If you buy a factory unlocked device the bootloader will be unlockable/carrier branded devices may be locked and not unlock able.. Pretty simple really.
Sorry that I can't help much.
Un-lock Xpeia SP
If you Un-lock the Xperia SP for all Networks, does this make bootloader Unlock available?
If not, any Ideas why?

Nope. SIM-UNLOCK is separate to bootloader unlock.
It just doesn't.
On some old xperia phones you could open sim and bootloader like xperia arc if you used test point method to unlock sim it unlocked boot loader as well.
2013 xperia models that don't have removable battery are no longer able to use test point so you can't unlock boot loader or sim.
To unlock sim you need code which you cab buy from internet.
To unlock bootloader you need to contact your airtime provider and see if they will help in unlocking bootloader again this needs code but not freely available.

Bootloader and simlock are two completely separate things. If your bootloader status does not allow bootloader unlocking you will NEVER be able to unlock it. This means that you will not be able to flash CM, AOSP or any other custom kernel based rom on your device.
You can still enjoy stock rom based kernels like the following:
http://forum.xda-developers.com/showthread.php?t=2463675
http://forum.xda-developers.com/showthread.php?t=2481248
and root your phone.
Here is a most commonly asked questions video which may clear out some things for you:

test point exploit has been closed.
If it says its not allowed there is no way to unlock it. Allthough it is not related to sim unlock it generally occurs that branded phones are locked and unbranded are can be unlocked.
One main exception is Vodafone UK, they have given me 3 xperia T's and one Z1 on contract, all of which can be unlocked
