i have been testing my application on 4 IOS devices. 1 ipod touch 2g, 1 iPhone 3gs, two iPhone 4's. On the iPhone 4's my application will take up about 30-50mb of memory while running. On the 3Gs it will take about 15-30mb, and on the iPod it will take about 15-27mb of memory.
Is there any kind of rule against how much memory your application can use? The app doesnt crash on any of them, but i thought i read somewhere that the max is like 20mb of memory usage?
Frankly im surprised that the iPod touch 2g is able to run the thing, i was told that the max youll ever get out of iPod 2g is like 20 mb of ram.
Now i have another question, while running Instruments, does it add any amount of memory usage on the device? It seems like while running instruments the application lags more than when not running with it.
Thanks, Jacob
