This is another new tweak now available via Cydia. Hosted on the BigBoss repo it costs just $1.99. HomeScreen Settings allows you to create a new icon on your Springboard which directly links to a specific menu within the Settings app.

Here is the official blurb:

Requires iOS 4 or higher
Add any settings icon to your homescreen!
Now when you enter Settings, you can choose whether you can add each preferences page to your homescreen! The bottom of some preference pages will have a button ‘Add Icon to Homescreen’
A special icon will be added to you homescreen. When you open it you will get a folder-like slice view with your application’s settings right on your SpringBoard! You can add these icons to folders, move them, delete them, create folders full of settings icons , and most important, it works with all settings bundles for stock , jailbreak and non-jailbreak apps.
Add more functionality to your homescreen!
Note: Some particular icons are not accessible on iOS version < 4.3 at the moment. (“General” tab and third party appstore settings ). A few settings that don’t offer the “Add to HomeScreen” option, cannot be added for performance and usability reasons.
Works on iPhone, iPod and iPad.Works on all iOS 4 versions and also on upcoming iOS 5 . Compatible with all popular addons / tweaks.

Rather than trying to explain just how cool this tweak is, here’s a quick video to show how nicely the tweak embeds into the UI:
