[Q] Can't unlock sim Arc as I did with Xperia x10!

Hi all
I,m a new owner of a Xperia Arc. It's locked for another carrier as mine!
Sometimes ago, with my Xperia x10 witch was locked the same way, I did just root it, install a custom ROM (Wolfbreak, CM6) and it was automatically unlocked...
Why can't do the same thing with Arc?
(It is already rooted with generic 3.0.A..2.181, but unfortunately remain locked!)
SIM/network locking is completely independent and separate from any firmware. It is also once and permanent, unaffected by any future updates or flashing.
I don't know what you did to the X10, but flashing a firmware doesn't unlock it. You must purchase an unlock code.
In Canada, it's ~$5 USD but that varies depending on carrier and location.

Xperia Arc S sim-locked

I recently bought Xperia Arc S but it is sim lock to my service provider in Bulgaria. Can I unlock it for free or I have to pay on omnius server. And also I want to unlock bootloader but in service menu it is writen BOOTLOADER UNLOCK ALLOWED NO.
I'm fairly certain that yes, you have to pay to get Sim-Unlocked. I'm not all too savvy yet on technical phone stuff, but I'm fairly certain that you'll be stuck with a locke bootloader.

How do I unlock the phone

Hello
I recently came into possession of a sony xperia lt15i which is currently on Virgin (UK) and I would like to unlock the device. Its currently charging so I cant advise the OS.
Can anyone offer some help please
the software version is 2.3.4
You can unlock the Bootloader by one of three ways and Sim unlock by one, which is to pay for it.
Hi mate,
Mine was locked to Virgin UK, I unlocked via the test point method. Below is a quick guide I made in a previous post:

This method does unlock the Boot loader though, not sure if you want to do that yet.....
Hope you find it helpful
BTW: it doesn't matter which firmware your running.
