hi mate,
Flash Player for Symbian^3 devices is actually integrated into the firmware. four or five years back, it was still possible to download and install the standalone Flash player, but now it is not. this is in addition to the fact that Adobe has ceased development on Flash player for all mobile platforms, so really the only updates that are to be seen for Flash Player were in firmware updates for Nokia devices. the best you can do is to check via Nokia Suite on your PC that you have the latest firmware for your device installed.
