No customization, Bug in script, Does not work on iPhone

Does not work on iPhone4. If the black icon does not contrast your site (e.g. you have a black background) you have to manually change the CSS to use the white icon. At least the white icon is delivered with the package. Also there is a minor bug which occurs due to an uninitialized variable and this is shown if debug is set to true. A simple settings pages and a bit more testing could have made this plugin both simple and flexible. For me it is unusable.
