I have created the ipkg entries for the default sharp apps so if anyone wants to uninstall the default sharp apps, then install sharp-pkg-c3100_1.5.ipk (inside the zip file).
Once you install this package, you will see the following entries in the Installer/Uninstaller (You can uninstall sharp-pkg-c3100 once it is installed. It won't be needed anymore):
You can then uninstall the sharp packages that you want to get rid off. This will remove them completely from your flash, so even if you do a factory reset, they won't come back. You will need to do a nand restore to get them back provided you had a backup or reinstall the sharp rom.
So be careful if you chose to use this. It's meant to remove the apps completely to give you extra space. And of course, always make a backup first.
USE THIS AT YOUR OWN RISK.
You might have to remount / as rw first before uninstalling the apps. Once you're done, you can remount / as ro.
