Disabling Multitasking on iPad1 running iOS4.3.3

Although I had a iPad2, but I still uses my iPad1 as my primary devices since I had so many hacks going on my Jailbreaked iPad1, it is still running good, but memory issues (256>512) is really a bottle-neck of this nice device…

By turning of the multitask which was introduced in iOS4 (Which I think Multitask on iOS is a joke, you call that “multitask”?) I am getting a very good improvements on my iPad1, which in some case, it works as fast as the iPad2…

I notice there are software in Cydia for user to disable multitask on iOS4, but since I like to put my hand on these easy task, why install an extra software, here is how I quick disable it on ,my iPad1:

I already had SSH config and running on my iPad1, so it saved me time, by editing /System/Library/CoreServices/SpringBoard.app/K48AP.plist by nano, edit line contain multitasking from true to false, reboot then done done.
