typical memory usage of an iphone app
<p>According to Instruments 'Net Bytes' of my app are never more than 2MB yet sometimes I receive memory warning and the app crashes because some views on the stack are unloaded by force.</p>

<p>I'd like to know what is the typical memory footprint where system would not send you memory warning and unload the views ?</p>

<p>I have so far tried this on OS 3.1.2 on iphone 3GS and 3G and with 3G giving warning almost 80% of the time I test the app on it.</p>
