But today I am going to share with you a little trick you can use to send any Java application from your s40 Java mobile phone to other mobile phone.

Download Blueftp with the image link below.

So How Do I Send Java Application From My s40 Java Mobile Phone Using Blueftp?
  • After download the blueftp to your mobile phone, then install it.
  • Now go to or any other file sharing sites to download any Java application. When downloading from, there is an option as to whether you want to download either the .Jar file, or .Zip file.
  • If you choose the .Jar it means you are going to download the real application, but if you choose the zip file, it means the real application is going to be in a zip file which is what we want.
  • So therefore, you should download the zip file
  • After downloading the zip file, open your Blueftp and locate the zip file you have just downloaded from your mobile phone.
  • After locating the zip file, open it and extract the jar file you will see inside.
To extract it:
  • Just press the upper left soft key on your mobile phone.
  • Then choose extract this item or you can use the shortcut by just pressing “1″.
  • When you choose the extract selected item, it will take you back so as to choose any folder you want to extract the file to.
  • Choose any folder and press the upper left soft key again and select extract item here or simply use the shortcut by pressing “3″.
After extracting the .jar file, you will see the file extension being renamed to _jar in the folder you extracted it to, now all you need to do is to clear all the text leaving only one letter with the _jar extension e.g. If the jar file is operamini.jar before, and after extracting it, it becomes operamini_jar.
Just press the upper left soft key and choose rename, then clear the operamini leave just one letter lets say the starting letter which is O. It will now become O_jar.

You can now send the file to any phone by:
  • Pressing the upper left soft key and choose send via Bluetooth. 
  • Search for the receivers phone and send it.
  • After sending it, rename the O_jar from the person phone to O.jar
  • Then you are done, you will now see the file as “Operamini”.
  • The person can then install it on his phone.
