The iPhone SDK includes a singleton of class type UIDevice that you can use to retrieve device specific information (this works equally as well with the simulator).

Available Properties in UIDevice

• uniqueIdentifier – identifier guaranteed to be unique for every device
• name – arbitrary name found in General > About setting on device
• systemName – name of the OS running on the device
• systemVersion – current version of the OS
• model- model, such as ”iPhone” or ”iPod touch”
• localizedModel – same as above using a localized string

Stats for Simulator

This code will list all stats shown above:

NSLog(@"uniqueIdentifier: %@", [[UIDevice currentDevice] uniqueIdentifier]);
NSLog(@"name: %@", [[UIDevice currentDevice] name]);
NSLog(@"systemName: %@", [[UIDevice currentDevice] systemName]);
NSLog(@"systemVersion: %@", [[UIDevice currentDevice] systemVersion]);
NSLog(@"model: %@", [[UIDevice currentDevice] model]);
NSLog(@"localizedModel: %@", [[UIDevice currentDevice] localizedModel]);

Running the above on the simulator returns:
