Heya, I figured I'd show you how to find out if the boot loader is locked. After some toying around and reading around in the Xperia Arc forums, I figured it out myself.

To try this, make sure you have fastboot installed. It's part of the Android SDK so if you don't have it, install it. Alternatively, it's also included in the application PDANet

Hold the search-key on your xperia play and connect the USB cable. The LED should switch on in blue. If you computer complaints that it can't find drivers for the device install the "Android Bootloader Interface" Driver that you can also download with the Android SDK.

Now type in "fastboot devices". If you can see a Hexanumeric code there, like in my screenshot, the boot loader is unlockable.

fastboot oem unlock sadly doesn't work. That would've been the day. :P Still, it seems it expects a code and no code is "0xFFFFFFFFFFFFFFFF" Maybe someone clever can find out how to calculate an unlock code from the Imei? :P Anyway, have fun with that for now.

That is to be expected. We'll have to wait for Sony Ericsson to help us unlock the Boot Loader eventually.

They announced that they'll only do this for non-simlocked devices.

I don't know how exactly it'll cost them money tho, if some people use a custom OS on their phone?

It will cost them money because when they abandon the phone the developed community will keep it alive. Meaning no one will buy the next phone.

^^^ Kind of exaggerated.

Where did it say only for non-simlocked? Where can I buy a non-simlocked xperia play?
