AppAdvice has teamed up with CM4 in order to offer you a chance to win a Q Card Case ($39.99) for iPhone 4 and iPhone 4S.

There are a select few things we grab every single time before leaving home: keys, purse or wallet, and iPhone. That spectacular multifunction tool for our on-the-go lifestyle is always in our grip, well, almost always. In preparation of an unlikely drop or the situation of sharing space with harmful objects, our iPhone needs body armor. However, what if it wasn’t just about protection, but also dealt with the storage requirement?

By featuring both a soft rubber padding for your iPhone and a premium fabric rear compartment for up to three cards, ID and credit, the Q Card Case can protect numerous valuables in less space and with tighter management. In addition, the design offers clear port access, button covers, and a front wraparound design. Therefore, when laid, dropped, or slid on a flat surface, the front of your iPhone should remain perfectly pretty.

If you’d like to get a more in-depth breakdown, feel free to read the AppAdvice hands-on review, plus check out the iPhone 5 version in the AppAdvice accessory round-up.

The Q Card Case is packaged with a screen protector and microfiber cleaning cloth, and available in Black Onyx, Pearl White, Pacific Green, and Pink Sapphire. For this giveaway, it’s the option of black, white, or green.
