Top 20 tough iPhone 4 and 4S cases

I first posted this roundup not long after the iPhone 4 hit stores and it's been through several updates, and now only includes cases that fit both the iPhone 4 and 4S and carry the "universal fit" tag. Recently added: Griffin Survivor and Gumdrop Drop Tech Series. As I've said before, how you choose to protect--or not protect--your iPhone is a matter of personal preference. But if some heavy-duty shielding is what you're looking for, this is the list for you. While I tried to pick tough, protective cases that look good and don't make your iPhone too bulky, a few of the cases have more extreme designs that aren't necessarily intended for everyday use. I should also note that some of the more rugged cases can be a bit of a chore to remove and aren't friendly toward iPod docks and certain charging accessories due to how recessed the ports become when the case is on.
