Set the date on your phone to before 12.6.2007
Install theme
Set back current date
This should work for all theme/game/app certificate expired errors

Hi everyone..

I'm new here.. I'm having problem downloading themes for my Nokia 5610.. Im using my phone browser to download the themes by going to wap.mobiles24.com,
I've entered the correct 'Download ID' it says 'File Format: nth'..
but when I start downloading a Theme.. "File Format Unknown" error comes out..
I dont understand, why i encountered that kind of error, coz my phone support .nth file format for themes.. and I've already tried downloading themes from other site [e.g. wap.*****.net] by using my phone browser and following same procedure and I dont encountered that kind of error.. please help me.. what could be the problem..
