File permissions after installation

I just downloaded and installed mobile joomla. I haven't tested it yet, but notice that the file permissions for the component are set to 0666. I usually set files to 0644. Will the component still work if I use 0644?

Mobile Joomla doesn't change permissions at install and should work with any permissions (allowing php to read files and to write to administrator/components/com_mobilejoomla/config.php)
