    Default Multitasking not working...

    Well not quite. Streaming audio works fine, but background updating(google app) and calling(skype) are not.

    I have googled it and I seem to be the only person with the problem.

    On an unlocked iphone, jailbroken through pwnagetool.

    Any help would be appreciated.

    Thanks!

    I'm assuming this is a 3GS on iOS 4.0? Until yesterday, the Skype app wasn't ready for iOS 4.0, so unless you've upgraded very recently you may not have the version that supports backgrounding. Also note that from my understanding programs running in the background can only keep a network connection active for 10 minutes, after which time they push you a notification letting you know they're about to disconnect from idle. I've had several network apps that are background capable do this, a good example being Colloquy.

    Audio apps like Pandora and such continue playing when you background them, so that illustrates that it should be working. I would assume more that the issue you were having was with the apps than anything else. See if you can find any other iOS 4.0 capable and ready multitasking apps and test them as well.

    Good luck!

    I actually have the same problem with new skype on my 3GS. Need to find time to reload fresh 4.0 custom ipsw and see if something I have hacked has caused this problem. Can't see any obvious reason otherwise.

    Other backgrounding functions seem to work fine.

    Just verified on my iPhone 4 that Skype will receive calls in the background while it's backgrounded. Dunno if it's hardware difference, etc., but the version that's there definitely is backgrounding properly for me on the iPhone 4 hardware.

    I'll test on my 3G when I get home tonight, but that won't be for a few hours.

    Skype multitasking (or running it in background) does not work on my jailbroken iPhone 3GS running iOS 4.0. This appears to be a widely reported problem.

    Yes, I did update Skype. AFAIK, the only background service working on jailbroken 3GS is the ipod/audio streaming one. Can any of you guys check the google app as well?

    Looks like the culprit could be skype detecting mobilesubtrate and disabling voip and audio backgrounding. Probably can be fixed with a mobilesubstrate update.

    Skype always displays a warning (about jailbroken devices - but they really mean mobilesubstrate) when you launch skype. This time it seems that they have gone further than just a warning.

    This is an educated guess based on feedback here and at official skype forum - the author of mobilesubstrate has not said anything yet about the new skype update.

    Okay jailbroken (but no mobilesubstrate) - Skype background/multitasking works fine. Might be a conflict with a specific mobilesubstrate addon.

    Feedback from twitter seems to suggest it is a problem with the core MobileSubstrate - Saurik has not confirmed or said if it is possible to fix this (yet)

    Which specific part of multitasking? Do you go appear to offline in Skype when you click the home button?

    Or does skype appear to start up each time you open it?

    Are you running Skype 2.1?
