Apple don’t support multitasking and home screen wallpaper. Ok, let we enable ourself. You need jailbreak and you also need know about SFTP.
For iPhone 3G
Open,
/System/Library/CoreServices/SpringBoard.app/N82AP.plist
and then search
<key>multitasking</key>
and change to
<key>multitasking</key>
<true/>
For Home Screen Wallpaper , you should change like that.
<key>homescreen-wallpaper</key>
<true/>
For iPodTouch 2G
Open
/System/Library/CoreServices/SpringBoard.app/N72AP.plist
search
<key>wifi</key>
add this after <true/>
<key>multitasking</key>
<true/>
<key>homescreen-wallpaper</key>
<true/>
It will be like that
<key>wifi<key>
<true/>
<key>multitasking</key>
<true>
<key>homescreen-wallpaper</key>
<true/>
After Saving and uploading , restart your device. You will see multitasking and home screen wallpaper after reboot.
Update: If you want to show battery with percentage, you can use following key
<key>gas-gauge-battery</key><true/>
Cheer!!!

Bro,
[~I'm just asking out of curiosity.~]
Would there be a way to disable the wallpaper? As it seems to me, that’s causing the slowness!? or there is some other things that make the slowness?
