Well if you had taken the time to look into the docs, you would have seen that Grand Central Dispatch has been introduced to iOS with Version 4.0. So there is no way they will work on iOS Version 3.2.

Alternatives: Use some of the async methods like performSelectorInBackground:withObject: or roll out your own threading methods with pthreads.

Grand central dispatch is not available before iOS 4.0. You can use NSInvocationOperation for async operation.

GCD and blocks aren't available in iOS 3.2. For simple multi-threading, you can use performSelectorInBackground:withObject: and performSelectorOnMainThread:withObject:waitUntilDone: instead.
