iFrogz iPhone 4 cases work with Verizon phones -- we're now giving away four

No sooner had we heard about the minute differences in the design of the Verizon (CDMA) iPhone 4 than the TUAW inbox began filling up with news of cases that would work with both the original GSM/AT&T iPhone 4 and also with the Verizon models. Some of the first VZW-compatible iPhone 4 cases we've actually laid hands on come from iFrogz, one of the long-time iPhone accessory manufacturers.

To celebrate the release of both the Verizon iPhone 4 and the ability of the iFrogz cases to work with anyiPhone 4, TUAW is giving away four of the protective beauties. What do we have on hand? From left to right in the image above:

• For the car fanatic, there's the US$19.99 SiliconeTreadz case. It's a 100% silicone case with a tire tread pattern, and is treated with anti-dust technology.
• For someone who likes a soft feel to their iPhone case, there's the $29.99 LuxeOriginal. It's a hard plastic case in gray and black with a soft-touch finish.
• For the person who wants a hard case with an attractive etched pattern, consider the $24.99 SoftGloss Phase. It's clear and blue with a spiraling pattern of dots, and the Apple logo on the back of the iPhone 4 shines through.
• For protection and style, the $29.99 Swerve may be the case for you. It has a nice sleek exterior and a colorful (powder blue to dark blue) hard plastic insert for two layers of protection.
