In a smooth move by Sony Ericsson to 'go against the grain' and support modders better, their Android Bootloader Unlocking website just went live. Users with unbranded Xperia devices from 2011 and onwards like the Xperia Play, Arc, Neo, and Pro, can try out custom ROM's and mods easily and with some help from Sony Ericsson themselves. The only thing you will need is your phone's IMEI number, which gives you annlocking key to go with the Android SDK's fastboot program. The instructions are more detailed at the site link below. They do give the standard 'shpeel' that you could potentially brick your phone, so be cautious as always. For now, let's give a shout out to Sony Ericsson for supporting the Android community. Now, if we can only get them to release some even more exciting phones...
Thanks to my tipster, Tio Gardi!
