Two new iPhone 4 cases have launched on Friday from SwitchEasy and Quirky. SwitchEasy's Colors case uses a shock-resistant silicone material with a smooth finish. It provides access points for the iPhone buttons and protects the headphone jack and data port. The design also includes SwitchEasy's 'jellybean' home button, a glossy cover in a contrasting color over the iPhone's home button. The volume and power buttons are an extra-thick design claimed to improve tactile response.
