A new application, Backgrounder, is now available for jailbroken phones! This allows you to run official App Store apps in the background. Yes, you can now listen to music while you are in your favorite App Store app!
blockquote>With Backgrounder, you don't have to log into a secure shell session. You don't have to perform black magic. You just press and hold the home key while running any application. After a few seconds, the Backgrounding Enabled pop-up appears. Release the home button and go about your business. Backgrounder automatically returns you to SpringBoard. To quit the background application, re-launch it from SpringBoard, then press and hold Home until the Backgrounding Disabled pop-up appears.
