I’m working on an iPhone app for WelcomeToYourMac, and during compilation I kept getting a warning saying:
warning: Turning off phone number detection is not supported on iPhone OS versions prior 3.0.
I couldn’t find the answer on Google, so I kept poking around in Interface Builder until I finally found the answer, and I thought I’d go ahead and share it here – just in case your as compulsive about squasing warnings as I am! :-)
First I double checked my build properties were all set to iPhone OS 3.0. right click on your target
to show and click Get Info to show:
Once confirmed, I opened the problematic .xib in Interface Builder and found the culprit. Press the unassuming info button 
then set the Deployment Target for that specific .xib!
It had been set to OS 2.0. Switching the .xib’s target deployment to 3.0 fixed the problem.
Easy!

Thanks a lot for your post. It really helped me
Maybe you also know howto solve that warning:
The ‘navigationItem’ outlet of a UIViewController has been deprecated. Navigation items are required prior to loading a view controller’s view. Instead of an outlet, consider embedding the navigation item in the view controller.

@nite_man, I do remember running across that error too, but don’t remember all the specfiics of how I fixed it. The gist is that I had to remove the navigationItem from the xib in InterfaceBuilder, and then build one programmatically in the .m file instead of using an IBOutlet. Hope that helps!
