Normally all Series 40 phones have very less processing power, less memory storage compare to series 60 Devices.

This articles is about how developers can enhance their application performance at a great level by just considering most important aspects of the application. when MIDlet starts it calls startApp() method first and then it calls other methods. So if there are any security checkings,any splash screens etc to be displayed it should me executed using startApp() method only and only in manageable manner as code given in this article.To increase application performance avoid using unwanted method calling, create objects as less as possible.

Overall this Article provides all the important considerations while developing applications for series 40 phones.Code examples given worked as expected and i have corrected my mistakes after reading this article.
