About a year ago Apple introduced the iPhone OS 3 which added MMS, Tethering and copy and paste support to its iPhones. Today at the iPhone OS 4 developer preview Apple has introduced an array of new features, the most important one every body has been waiting for being Multitasking.

iPhone OS 4 will bring multitasking, folders and home screen wallpapers just to mention a few, but is this little to late? The problem with the new multitasking is that it is not really multitasking as not everything can utilise it.

Apple will only be introducing 7 services that will take advantage of its new multitasking functionality, they are Background audio streaming, Voice over IP applications like Skype, background location, push and local notifications, task completion, and fast app switching.

Apple is also introducing an array of other updates to some of its apps like the mail client and introducing iBook to the iPhone that is originally an iPad app.

Bad news for people still owning a 2nd generation iPhone or iPod touch hey will run many things, but not everything — they will not support multitasking, the hardware just can’t do it.

iPhone and iPad users can expect the iPhone OS 4 update in fall this year.

Me I am still very happy with my HTC Hero running Android, all of the extra functionality that is only being introduced to the iPhone OS 4 now Android users have been enjoying for long now.
