How can I determine what iPhone, iPod, iPad Model is using my application? I would like to get output like: iPhone, iPhone 3G, iPhone 3GS etc

In the unified api you have to update the dll import.

Replace it as following:

[DllImport ("libc", CallingConvention = CallingConvention.Cdecl)]
internal static extern int sysctlbyname([MarshalAs(UnmanagedType.LPStr)] string property, // name of the property
                                            IntPtr output, // output
                                            IntPtr oldLen, // IntPtr.Zero
                                            IntPtr newp, // IntPtr.Zero
                                            uint newlen // 0
    );
