When I try to install an application (E. g. theme, game, VPN client) to my Nokia device I get an error message: "Installation security Error. Unable to install" or "Certificate may yet not be valid, is expired or phone's day settings may be incorrect"
If you get such an error message, please set the device date to before 12.6.2007 (or for some applications maybe even earlier), and then this error doesn't appear and installation continues normally. After installation you may set date back to current date.
If this does not help then
TOOLS>APP MGR>OPTIONS>SETTINGS>SOFTWARE INSTALLATION and changed it from SIGNED ONLY to ALL.

Hello guys. I have Nokia 7600 slide.
Today, I have downloaded an application from Ovi Nokia store, for free - a flashlight program of some sort
Anyways, I have the problem with, guess what, certificate
If it's my current date, then the problem is just "Expired Certificate"
but if I set it back to 2-3-4-5-6 years back, then it's: "Certificate may not yet be valid,expired or phone's date setting may be incorrect"....
Please help me out somehow :<
Btw, when I type #06# and call it, I get "Unknown application", what the f ?
