I've built an application using S60 3rd FP1 SDK and the applications builds and runs perfectly when testing on a Nokia N95 phone, but just displays a Menu:Feature not supported error when running on either a Nokia N73 or a Nokia 3250.
The same SDK has been used to build other applications which work on all 3 phones, and I'm not using a capability not used in other apps. The applications doesn't even get to the first line of code, so it's not an API difference causing this error. I figure it's something to do with the resource / icon, but after a day of trial and error, I'm not getting a further at figuring this out.
It looks like I'll have to begin a new project and slowly migrate the code over, but I thought I'd first check to see if anyone else could shed any light on this problem.
