All4Cellular offers the LifeProof Waterproof Case for Apple iPhone 4 / 4S in Black, Pink/Gray or Purple/Black for $39.95. With $2 for shipping, that’s $5 under our October mention and the lowest total price we could find by $8. (However, we saw one in Black for $2 less in October.) It features 6.6-foot drop shock protection; it’s also waterproof to depths of 6.6 feet.
