Due to the last release of the adMob package, I have added the MessageUI framework to my project. As I wish to deploy my application to 2.x OS devices, I have weak linked MessageUI as advised.
If I build for iPhone device 3.0, it works fine.
If I build for iPhone device 2.2.1, I get a link error: "ld: framework not found MessageUI"
Where could I be wrong?
