UNLOCKING THE BOOTLOADER:
This may wipe your phone, so backup your stuff
• Go to Sony's dev site
• Request the unlock key and check your mail straight away. Email is quick these days.
• Open Flashtool on your computer (yes, the one you installed earlier)
• Click the "BLU" icon
• Follow the steps and enter your unlock key
