We just informed you that vodafone DE officially released OS 188.8.131.526 for the 9000, well it looks like they gave the green light to the 8520 as well. Even though these Operating Systems leaked a few weeks back, it's always nice to see carriers making them official. It's been a fun filled day of OS releases. I wonder what else will come down the pipes. Give this OS a try and delete that vendor.xml file if vodafone DE is not your carrier.
