Apple now owns iPhone4.com and WhiteiPhone.com (via TechCrunch). Neither of those domains were theirs. Now, when you navigate to iPhone4.com you are taken to the iPhone product page on the Apple store website. WhiteiPhone.com takes you to Apple's white iPhone 4 page.
Apple has continued to work to pick up domain names related to their products and services. Anyone who has had to come up with their own domain name knows that it's just a huge pain in the butt. Everything seems like it's taken. Worst part is, most are just placeholders and domain squatters.
