Today, I will be hopefully be getting an iPhone 4! I have some questions I want to clear up first. 1. Which size should I get? I can afford both, and I have 13 GB of Music and 12 GB of movies. 2. Is there any case that I should get? Like one better than the rest? 3. I am planning on getting MobileMe, is it a good buy? 4. Is there anything else I should consider buying?
