[ How to Minimize your s40 mobile phone aplications ]

Good news for all nokia s40 v5 and 6th users. Yup! we can now minimize java applications or send them to background. And can almost run 5 applications at the same time


1] Open the jar application with WinRAR via PC


3] Edit MANIFEST.MF using notepad and add followings lines.

Nokia-MIDlet-auto-start: no
Nokia-MIDlet-no-exit: true

4] Save it and drop in the same folder That's it. Now whenever you press red button on your phone instead of closing the application goes to background.

Manifest-Version: 1.0
MIDlet-Name: Periodic Table
Created-By: 1.4.2_07(Sun Microsystems Inc.)
MIDlet-Vendor: NOKIA
MIDlet-1:periodic table 2.0, /Pt.png, Pt
MIDlet-Version: 2.0.1
