Some of you might have been using Volume Boost since the 2.x days and are missing it for 3.0. Here's the procedure for enabling it for 3.0. It's reported to boost the volume by 20%, which is a lot.
1. Start by downloading the attachment below.
2. Extract the contents somewhere convenient.
3. SSH into your iPhone through WinSCP or cyberduck.
4. Navigate to the /System/Library/PrivateFramework/Celestial.framework/ folder.
5. Locate the file RegionalVolumeLimits.plist and rename it to RegionalVolumeLimits.bak.
6. Copy over the RegionalVolumeLimits.plist file you extracted in step 2 to the iPhone's /System/Library/PrivateFramework/Celestial.framework folder
7. Set permissions to the RegionalVolumeLimits.plist to 0777.
8. Reboot the iPhone.
9. Dance.
