One thing that the iPhone doesn't have that many other smartphones do is a removable storage card. The advantage of such a card, of course, is that you can store much more data on your phone than if you're limited to internal memory. However, you can now look forward to the imminent arrival of an SD card reader for the iPhone that plugs in via Apple's dock connector. The device is available for preorder from ZoomIt at the currently discounted price of $50. You can read more on Wired. This accessory works in conjunction with an app to let you access your music, movies, documents, and photos.
