The lack of multitasking on the iPhone has always been a sore point for many users, and Apple has refused to officially allow multitasking for third-part applications, citing security reasons and battery life issues. Rumor is now going around that the upcoming iPhone 4.0 firmware update might include multitasking, and it’ll even get a cool mechanism for switching between apps, something along the lines of the ExposÃ© feature in Mac OS X. Apparently you won’t be dealing with the application windows like ExposÃ©, rather you’ll see application icons (which is still fine, as long as multitasking works). Let’s not forget that Apple currently has a form of pseudo-multitasking, in the form of Push Notifications, allowing apps to send notifications to the phone, instead of continuously polling for updates. It does do a rather good job for hiding the lack of multitasking, but let’s see what Apple comes up with in iPhone 4.0, shall we?
