You may directly download the new software without first deleting the old version, and your BlackBerry
will prompt for permission to upgrade. If for any reason the upgrade fails, you should delete the software and re-install.
To delete the old version
Option one, deleting directly off the phone:
a) Go to Options->Applications
and choose any application
b) Select "Modules" from
the track wheel menu
c) Scroll to the bottom and choose
Yak On! and select Delete from the trackwheel menu. You don't need to
reboot the phone yet, do that after deleting YakOnPrefs
d) Repeat step c for YakOnPrefs
e) It is important that the phone
reboots after deleting YakOnPrefs and before installing the upgrade
Option two, deleting using the Desktop Manager:
a) Download YakOn.zip (If you have
not already) and unzip it
b) Connect your Blackberry to your
PC via the USB cable
c) Start the Desktop Manager and
choose "Application Loader"
d) If Yak On! is not listed, add it
by pointing the Application Loader to YakOn.alx from the zip file you
unzipped above
e) Make sure the check marks are
unchecked to the left of Yak On!
f) Select "next" to delete
Yak On off the device.
After deleting the old version, download the new version
