This case is pretty useful, but the others in the gallery? Not so much. A charger is nice to have, but an extra hand. That's a little weird. Check out the gallery for more iPhone cases.
The weirdest one in my opinion is the condom iPhone case. While it could come in handy, it's weird to think that people would buy an iPhone case specifically to hold condoms.
But the Australian company Annex Products have created the $30 Playa Case that does just that. That way, you'll be prepared with two condoms and your iPhone. Sounds a little weird to me...
What do you think of these phone cases?
