I'm trying to figure out if jailbreaking my 2nd generation iPod touch and enabling wallpapers/multitasking affected it's performance. I've noticed that when I open an app, the SpringBoard icons initially slowly swell out from the middle, and then quickly explode. I'm not sure if this is how the transition was meant to be, or if it is a result of lag. It's so jerky, it feels like whiplash. Can you guys tell me if your animation on iOS4 is like that, or is it a smooth, continuous flow? This would help me to tell if lag while running certain apps is due to the jailbreak or is natural. And it may be useful for other users to know before they jailbreak iOS4 on their device. Thanks.
