This new case from Senre Design is for the iPhone 4/4S. The Hand Strap iPhone Case is a snap-on back cover that adds a comfortable strap to the back; slip your fingers under the strap for a secure, one-handed grip. The case rises above your screen to protect it even if you should lay your phone face-down. There’s even a little extra room inside where you can store a little cash. It’s available in black, blue, rose, or orange for $29.99.
