Not all features are compatible with all devices. For example, multitasking, custom wallpaper, and Bluetooth keyboard support are available only with iPhone 4, iPhone 3GS, and the third-generation iPod touch (32GB and 64GB models from late 2009).
I have a 3rd generation just trying to figure out how to access the multitasking
Yeah, They atleast could have told us howyou would think apple would make that infomation much easier to find and very clear.
how do you tell what "G" touch I have?
