Quick tutorial for unlocking new Xperia devices. Although there is one on the SE developer website, this thread can be used for users to discuss their problems during unlocking etc.

Warning! This procedure will wipe the /data partition of your phone.

1. Download:
-fastboot package: http://www.multiupload.com/BMJ24IL6XY

2. Go to: http://unlockbootloader.sonyericsson.com/instructions
3. At the bottom click 'Continue' and enter your IMEI (type *#06# to find out), name and email address
4. You should now receive your unique unlock key
5. Extract fastboot.rar and open fastboot folder
6. Hold SHIFT and right click on the background of the folder
7. Select 'Open command window here'
8. Connect your phone in fastboot mode (turn phone off, hold menu button and plug in USB Cable)
9. In the cmd windows type in fastboot.exe -i 0x0fce getvar version
10. If a value is returned, it means the phone is correctly connected

Warning! All your data will be lost.

Is it just me, or does the USB driver refuse to work in Windows 7 64bit? It worked fine in 32bit, though.

I use Win7 x64 and tried on my Desire HD before uploading the .rar. The phone was detected successfully.
