It reads on the web page ( that Asha 302 is shipped with a Series 40 1st Ed 1.1.

But there is no such a device filter as 'Series 40 1st Ed' on the same page. More over, there are relatively "new" editions of Seires 40 like 5th Edition or 6th Edition. So what does it exactly mean by Series 40 1st Ed 1.1?
