Question

Do any of Apple's devices support iOS 4.0 but not multitasking?

If not, I don't understand the [UIDevice isMultitaskingSupported] API (which was only introduced in iOS 4.0).

Thanks

Yes.

• Iphone 3G
• Ipod Touch 2

Due to hardware limitations, they can run iOS4 but not actually make use of things like multitasking. On my old iPod touch, running iOS4 added a significant delay to the device's operation, even without multitasking.
