Yes this code works Good,

display = Display.getDisplay(this);
public void startApp()
{
    display.setCurrent(form);
}
public void pauseApp()
{

}
public void hide()
{
    Display.getDisplay (this).setCurrent (null);
}

This is will work like, make a button can after clicking it call hide Function, or you call this hide function in constructor so it will hide itself when app start, can you keep unHide statement in appStart() so if you Tab the program then it will unHide app again.

NOTE: you said you are working on Network app, but some mobile will turn off the Internet Connection, when the Mobile screen Turn Off. please check this. and If you found any solution It will be Good to share here.

it easy just have a code of line on any event for example in the click of button

Display.getDisplay (this).setCurrent (null);

and return back the control via

Display.getDisplay (this).setCurrent (mycanvas);

try this

set your current Display to null. so there will not be any form or alert running on the screen. But however your code will be running in the background. 

Display display = Display.getDisplay(this);  // here 'this' points to Midlet

display.setCurrent(null);
