How To: Load (Almost) Any Game or App On Boost and Nextel

With over 57,000 freely distributed Java applications available, I’ll never be able to download, test, package, write up and post all of them.

You don’t have to wait for me to post your favorite  game or app.  This tutorial shows you how to load Java applications on Boost iDEN and Nextel phones using Sprint/Nextel’s ADP iDEN Content Uploader, which is a web based developer tool. This method does not require a data cable but it only works with phones on Boost Mobile or Nextel USA and requires access to a PC.

These instructions are based on using Windows XP because that’s what I have. As far as I know, everything should work the same on Vista or Windows 7.  Users of other operating systems will have to find alternative programs for creating .JAD and .ZIP files but otherwise the process should be the same.

  • Find the game or app you want to load and download it.  The best selection of free legal mobile games seems to be at Other good download sites include, and Many more can be found using Google.JADMaker

  • A Java game or app consists of two files; .JAR and .JAD. The JAR (Java ARchive) is the actual executable file.  The JAD (Java Application Descriptor) is a text file describing the JAR’s characteristics.  iDEN phones require both files in order to install. Some sites, including Getjar, only provide the .JAR, but the .JAD is easy to create using a program called JADMaker.

  • If you already have both the .JAR and .JAD files skip to the next step. If you only have the .JAR file – download Unzip the contents into a folder and then run JADMaker.exe by double-clicking it in Windows Explorer.  Still in Windows Explorer, navigate to the folder with the .JAR file and drag it into JADMaker, which will to create the .JAD in the same directory as the .JAR.

Creating a ZIP file with Windows

  • Create a .zip file containing the .jar and .jad.  There are many programs that can create  .ZIP files. I get good results using the ZIP file utility that is built into Windows XP, Vista  and 7. To use it highlight both files by holding Ctrl and clicking them.  Then right-click the selected files and choose Send to and then Compressed (zipped) folder (image above). If you get a dialog box asking you to “Designate Compressed (zipped) folders as the application for handling ZIP files?“, click “Yes

iDEN Content Uploader

  • Open the ADP iDEN Content Uploader at (image above).
  • Enter your Boost or Nextel mobile phone number in the field labeled PTN:
  • Click the Browse button and navigate to the folder where you created your ZIP file.
  • Click the ZIP file and then click “Open
  • Click the Upload button
  • The rest of the process is the same as if you sent the app to your phone from BoostApps;
  • Press the phone’s Menu button.

Main Menu - Games & Apps Highlighted In the menu, highlight Games & Apps (called Java Apps on some phones) and press OK.
