How to Fix Expired Certificate Error

Many people get this error while installing something on their phone. Let me tell you how to solve it. I'm assuming that you are using a Nokia Symbian Phone.

Open Menu >Settings



In settings Find Date & Time



Set your Year to “2006″. Because some applications are certificated for 2005-2006. After setting your Year to 2006 install the application who gives certificate error.




Finish your installation and you can set your current date back:)
