The application Backgrounder, a Mobile Substrate-based extension that brings muti-tasking on iPhone, iPod Touch and iPad, was updated to version SVN.R504-1.

Backgrounder SVN.R504 changelog:

• FIX: The settings file was not being loaded correctly.
• This is a long-standing bug that appears to affect all recent firmware (> 3.1.3?)
• This bug caused App Store apps to always use the Backgrounder method to background, even if set to use Native.
• Note that there may still be issues with some of Apple’s default apps on 4.0.

Backgrounder is available in Cydia via BigBoss repository for free.
