The uninstall processes on LG Incite mobile phone are not complicated, three ways you can choose below according to situation/setup. LG Phone Problem and solution
1. Uninstall Apps Using ActiveSync LG-Incite info
For Windows XP and below users will want to use the ActiveSync program. You can download ActiveSync 4.5 here.

1. Connect your LG Incite to ActiveSync
2. Click on the "Tools" option

5. Take out the checkmark in each program box you'd like to uninstall.
6. Click "OK"

It's really that simple, your LG Incite will take a moment to uninstall the unwanted Windows Mobile Apps you chose and then you're done.

2. Uninstall Apps Using Windows Mobile Device Center
If you're a Windows Vista desktop user there's no reason to download ActiveSync, partly because it won't work, but more importantly because Windows Vista comes standard with the Windows Mobile Device Center, a device to desktop sync application that functions in much the same way as ActiveSync 4.5.
Uninstalling Apps with Windows Mobile Device Center is a simple process if you follow the quick steps below:
