@daperl: it still doesn't replace (true) multitasking though, having to suspend\resume (if implemented by the app) whatever tasks you have to leave behind.

But yeah, it seems they've choosen a (semi) non multitasking implementation in favor of performance and lower power consumption. It's apparent the 2G\3G was operating at its limit just by jailbreaking it and running skinning app or one or two 3rd party background app\widgets. The slowdown is very apparent that way.

Not so with 3GS.. now they've no excuses not to implement multitasking in OS4.0. Well, the battery drain is still ridiculous... we'll see about that.
