I am using Sony ericsson’s XPERIA x10. I tried to upgrade my firmware from older version to 2.1 versions. I tried to download applications but no luck. They gave me error regarding security. Also, there are no unknown sources available in my application settings. I only have applications and development. What can I do? Is there 2.1 firmware version that I can upgrade? Can you tell me how to do that?
