I encountered a little problem on my iPod Touch when trying to multitask. Double tapping home to get the bar works, and switching to another app from the bar while on Springboard works, but when I double tap the bar while inside an application and try to switch to another application, the iPod crashes and goes into Safe Mode.

This has been from a clean install of 4.2.1 with redsn0w, sn0wbreeze, and sn0wbreeze without multitasking selected while making the ipsw. Those are three different clean installs, not jailbreak with sn0wbreeze and then redsn0w (cause that seems stupid).

Anyway, I've tried enabling multitasking through editing the Springboard.app/N**AP.plist through iFile (or whatever that path is) with the <key>multitasking</key><true/> method in addition to various winterboard activated multitask enablers (though I think that they are just doing the same things I'm doing manually).

Any fixes?
