I haven't had an iPod Touch before and I am super hyped to see whats announced and will be buying one as soon as possible. I have made a list of applications I want to get. But I don't know if any will work when the 3G iPod Touch comes out. Assuming the screen resolution and OS 3.0 is still the same wouldn't they work? Or will everyone need to update their applications? How long will it take until they are mostly all updated? Thanks.
