iphone can multitask if jailbroken and enabled with appropriate software. This has been shown to actually work extremely well. I asume that Apple is not alowing 3GS to multitask due to battery issues, but the device as a whole can be enabled to do that. I bet that 4G iphone will multitask and other iphone 3GS customers will be given an opportunity to do that too with appropriate software. N900, if able to improve the interface, make it less jittery, may be able to compete. However, as of this point, many times when I try to multitask on N900, the internet is stuck, unless i revisit and refresh the page. so bugs in N900 are limiting the title of multitasking
