Technique: Keep your iPhone 4′s lens clean
Cleaning the iPhone 4's lens and flash
.
The new, larger lens of the iPhone 4 camera is still teeny. The actual lens itself is protected by an external lens casing. While the lens casing is about 5 mm, the lens itself is about than 2 mm — just a little larger than the head of a pin. Even a small smudge or a fingerprint on your lens can really effect the quality of your images. Also, the iPhone 4′s lens casing is no longer recessed as in previous iPhones. It’s pretty much flush with the back of the phones case, making it even easier to get smudged and dirty. Fortunately, keeping the iPhone 4′s lens clean is even easier than previous models.
