Memory 1 and 2 - The memory utility provides a way to modify and change the current frames heap memory. When you run memory it will monitor how much frames heap is available every .5 seconds and display this information. It will also keep track of the minimum amount of memory it sees. There are two versions of memory. Memory2 will allow you to change how much memory is available. This is intended to help developers test for low memory conditions. You can only load one version of memory at a time. You can test for low memory conditions in your applications by tapping the down arrow. This will take away an additional 2000 bytes of memory each time you tap it. You can return this memory by tapping the up arrow.
