If you cannot install Gravity on your E-Series or Operator-Branded phone, please configure it to accept “All Applications” from the Application Manager’s settings.
Some Nokia E-Series phones and operator locked phones are configured to accept “Symbian Signed” applications only. They will show an error when you try to install Gravity: “Certificate Error. Contact the applications supplier.”
Solution: Configure your phone to accept “All Applications”
Open the Application Manager (”App. Mgr.”) from the Phone’s Menu or Settings and configure the Phone to accept “All Applications” as shown below:
You will then be able to install Gravity without any warnings.
