iPhones OS: how to programmatically differentiate iPad 3G from iPad Wi-Fi?

Question

Is there any property or other mechanism in iPhone OS to check during runtime whether application is running on iPad 3G or iPad Wi-Fi? Seems like UIDevice class does not provide

Answer 1

You can differentiate between WiFi and 3G iPads if your app is running on a second generation iPad:

+ (NSString *) iPadModelName 
{
    size_t size;
    sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char *machine = malloc(size);
    sysctlbyname("hw.machine", machine, &size, NULL, 0);
    NSString *platform = [NSString stringWithCString:machine encoding:NSASCIIStringEncoding];
    free(machine);
    if ([platform isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";
    if ([platform isEqualToString:@"iPad2,2"])      return @"iPad 2 (GSM)";
    if ([platform isEqualToString:@"iPad2,3"])      return @"iPad 2 (CDMA)";

    return platform;
}
