I wrote an application for making data call on Symbian6.1 (async RCall::Dial function, active objects etc.) and everthing works fine on Nokia 3650 and 7650.
Now I'm trying to run this application on Nokia6600 but Dial function return KErrArgument error!
What could be the problem?
Generally, should all application written and compiled on SDK6.1 work correctly on 7.0 as well?
Maybe this is trivial question but I did not find any document about compatibility and possible problems between those two Symbian versions.
