SDK confusion

[Eng.Ahmed]

i'm developing an application for mobile network quality assurance, now I want to develop for the broadest market of cell phones which as I understand the nokia s60 series, i'm confused when it comes to the feature packs, if i develop for s60 fp3 will it work on a s60 fp2 mobile or a fp1 mobile or not? and if not which one is the most common??
thanks

There is a complete binary break between 2nd and 3rd edition devices, so if you develop for 2nd edition it can not be installed into 3rd and visaversa.

Then inside a platform, safest options would be to take the olders SDK, so for all 3rd ed, I would suggest taking the MR SDK (without any FPs).

See chapter #2 in http://wiki.forum.nokia.com/index.ph..._Symbian_OS%3F and the link that ends that chapter.
