In order to install "Unsigned" releases, you need to go trough a one-time procedure. You will need to install the in the release included "SecMan.v1.1.SiS". This program allows you to install
"Unsigned" releases which are released after 05-16-08,without signing them every time. It also can do some hacking tothe platform security, such as disable and enable it again.This app should work on almost all S60v3 OS9.1/9.2 devices.Although, some newer firmwares block this method, so it will not work there. Do not use this when you don't know what you're doing. It may cause serious harm to your device.When the installation is done, look in the Applications folder on your phone, and find SecMan. Open it, follow instructions,and after reboot open it again and click on "Install Root Certificate".Then you can install the .sis file by opening it on your device,or on your pc using pc suite.Please keep in mind, if you format / upgrade your phones firmware, you'll need to do this step again and after that manually install those apps from Application Manager.
