Open Radar

 
The CLLocationManager reference document says significant location change monitoring "is available only in iOS 4.0 and later and requires a device with a cellular radio."

Therefore on a device without a cellular radio, like my iPad 2, significantLocationChangeMonitoringAvailable should return NO. Instead it returns YES.

Returning YES when it shouldn't means code like this won't work:
if ([CLLocationManager significantLocationChangeMonitoringAvailable]) {
[clManager startMonitoringSignificantLocationChanges];
...
}

When I run above code on my Wi-Fi-only iPad 2, there are no errors. Worse, the delegate methods to notify me that a new location is available are never invoked. It just fails silently.

Steps to Reproduce:
1. install XCode
2. create a new project for iPad or a universal app
3. add the CoreLocation framework
4. create a view controller and import CoreLocation header
5. observe [CLLocationManager significantLocationChangeMonitoringAvailble] will return YES regardless of there being no cell radio available
