Thought this might be useful to some people on here. Its a 200 page guide on everything iPod, iPhone, Apps, accessories and really everything Apple. Also includes a neat time line of Apple's history near the end.
Unfortunately, there's nothing about the iPhone 4. But I found some of the top apps review useful. Enjoy.
