Remove Push to Talk (PTT) from your AT&T BlackBerry

Here’s how to remove the Push-to-Talk (PTT) application from your AT&T BlackBerry if you don't use it (just one less application that needs to be open on your phone):

1. Download javaloader.exe from somewhere by searching Google for it and save it to your c:\temp folder.

2. Open a DOS prompt (Start > Run > cmd) and attach your BlackBerry to your computer with a USB cable.

3. Run the following commands, one at a time. Your device will reboot after each command.

c:\temp\javaloader.exe -usb erase -f net_rim_bb_phone_ptt_app.cod
c:\temp\javaloader.exe -usb erase -f KnJCDE.cod
