I am trying to understand what the concept of a "series" means and how they differ. Its my understanding that "series" has something to do with a standard set of capabilities in the phone and the way the phone's user interface works. Nokia seems to sponsor the "series" standards. I also read about "UIQ" as another set of standards different from "series".
What is a series and briefly what is the difference between series 30,40 and 60 phones?
Also it seems that the concept of "series" is somehow linked to Symbian, or atleast series 60 is. I've read about series 60 and 90 as well as UIQ at Symbian.com. However it seems that only Nokia makes series 30 and 40 devices whereas some other companies make series 60. I did not find much information about series 30 and 40 at Symbian.com
Are Nokia series 30 and 40 also Symbian devices or are the two not related?
Thanks for any clarification on this issue.
