Backup ur favourite browser any java app(s40 also)

Sometimes we have to format over phone and for many other reason we want backup of our browser or application.
Like-in case of uc7 or later version we want igprs to install it and sometime we haven't igprs.so just backup of the browser and share that backup file so that we don't need initialize it every time or with igprs.
This thing i get from a russian site and after a lot of efforts i understand its working.it creats a .rms file to backup but in s40 like a .jar,a .rms file can't be saved.so i mod this to work in s40 also.it is translated by me.
Use:
1.first rename ur jar file to a zip file.
2.just put given RMSBackup.class file in ur application using mini commander or any zipmanager.
3. Now open meta-inf folder and there u see a file manifest.mf open this file as text by pressing 4 in minicommander or use any other text editor.
4.there u see something like-
MIDlet-1: ucweb,........any thing
NOW after this lind add a line
MIDlet-2: RMSBackup,,RMSBackup
5.save it.u have done.rename ur file to jar again.
And open app.NOW there u see one more app in it RMSBackup.when u initialize uc exit it and open RMSBackup and create backup and when u again install the app then u can repair it using this app.
