Added new Glass Icons & Some more Icons to the non Glass version.
Download & Install Advanced Configuration Tool for Windows Phone 7 Beta from above link. Download is near the middle of the page above the comments & advertisement.
Copy the AppTile_*.png & AppIcon_*.png's to \Windows of the device using Windows Phone Device Manager or the USB Hack/TouchXplorer/Advance Explorer methods.
Open Advanced Config Tool & change to Tile & Icons tab.
Select desired app/hub & then select the desire AppTile & AppIcon png's. (Some Hubs/App are currently disabled in the Advanced Config tool because they have Live Tiles & changing those Tile images will cancel out the Live Tile Functionality.)
Select Change, then OK to confirm changes.
There's a second pop up asking you to restart to make changes, click OK if done, Cancel if you want to change more icons.
NOTE: According to the developer of Advanced Configuration Tool, schaps, it works with HTC & LG devices for change icons. The tool also has some support for Samsung devices, but NOT Icon changing. Please report any problems about it not working to the developer. This thread is just a collection thread for icons. I can't help getting it working.

Not exactly an XDA thing or on topic, but found an interesting Windows tweak for Media Center. I've always hated how if you mute Media Center, it mutes the system volume so you can't play music/youtube/etc in the background really. Well I found an app/shortcut "hack" that'll allow this. Download Media Center Mute & follow the instructions included. The just click the shortcut to mute/unmute Media center without effecting the system volume.
