Apple rocks… that's why they decide FOR you which protocol your music can be streamed over. We've changed that! Credit to cslamar for the write-up.

• Jailbroken iPhone
• iAmpache
  • iAmpache can be downloaded from the app store for free. Install it as you would any other app.
• voipOver3G
  • Make sure when you jail break your iPhone to include Cydia. This should be an option on all current methods of jail breaking. Open Cydia, click search, then type voipover3g. Install voipover3g. Restart your iPhone.

This tutorial will not tell you how to jailbreak your iPhone. If you can't google that then you shouldn't be messing around with this.
We take NO responsibility for what can/will/may/would happen to your iPhone. Do this at your own risk. It worked for me, and others, however Apple has a history of punishing users who modify their hardware.

This can be done one of two ways. First is to install OpenSSH on your iPhone through Cydia. The second is to use MobileTerminal. I will be using MobileTerminal as it will not leave your iPhone with an open ssh port to the world, and will not require you to change the root password. Open Cydia and go to search. Enter MobileTerminal into the search bar. Install MobileTerminal. After the install go to the Terminal application on the main screen. You will be provided a shell. Enter the following commands:

1. su
2. type 'alpine' no quotes. This will NOT display on your screen as you type. If inputed correctly it will provide you with another command line with root# at the end of the line. If it does not try again, and make sure you didn't change the root password when doing something else.
3. type 'cd /Library/MobileSubstrate/DynamicLibraries/' no quotes and make sure to keep the caps where they are listed. This is case sensitive.
4. type 'mv VoIPover3G.plist VoIPover3G.plist.bak' no quotes. Once again make sure to keep the caps where they are listed.
5. restart your iPhone

That's it!
You've now registered all programs that would only run over wifi with the cell modem!
