One of the more confusing aspects for both the geeks and casual users of iOS 4.0 is definitely the multitasking part. A friend of mine, after having recently bought an iPhone 4 complained to me about a bug which caused the whole screen to shift. Only when it happened again and I was around to witness it did I reveal to her the secret — that it was in fact the multitasking tray. And I’m not even going to start about the bizarre idea of mixing in there all recently opened apps regardless of whether they support multitasking or not. But thankfully for this last part, a clever team of devs - XCool Apps – have come up with a completely legitimate solution – AppSwitch.
