You can customize the looks of the icons that are displayed on your Devices’ Taskbar with a Skin released by Anastasia’s designer. Yes, these are too glossy/glass icons!

You need to download the CAB and install it to your Device, followed by a Soft Reset. Check the How To Install section at the bottom of the first post in case you run into problems (you might need to install a small CAB before actually applying the taskbar skin).

List of icons that are skinned and thus will be changed after install (quote):

- Skinned Battery

- Skinned Signal

- Skinned Phone

- Skinned Sound

- Skinned Notifications

- Skinned Network

- Skinned Bluetoth & Headset

- Skinned Services

- Skinned Active Data & Non Active Data

In case you want to revert to stock, just uninstall the skin and Soft Reset.
