Is signing a 3rd edition app still supported?

Hello everyone,

I have an app that was previously created using the S60 3rd Edition FP1 SDK (C++). It was successfully signed and released.
Now I would like to develop an updated version of this app, which fixes some bugs and provides new features/support.
I see that since that time, there have been several newer SDKs for newer phones (5th edition, ^3, etc.)

My question is this: if I develop this still using the 3rd Edition SDK, will Symbian still sign it? Or must I first port to a newer SDK?

Thank you in advance!

Basically you can use any SDK you want to, the signing wont have any differences between 3rd ed and Symbian^3.

The actual selection solely depends on the devices you want to support, and you should select the oldest SDK according to the devices you are supporting.

Excellent! Thank you very much for the very helpful and speedy reply.
