I have corrected this article a bit and now it looks better. I also want approve it. My small review:

From time to time it is necessary to use special unique value, associated with the current device (for example while generating activation key for your application). The device IMEI is a best choice in such situation.

This article demonstrates how to read the device IMEI in S60 3rd Edition. The realization is based on two idioms: active objects and observer pattern. Combination of these approaches is very popular in Symbian C++. The example of the class, demonstrated in the article is fully self-contained. You could just copy it in your own project.
