AppAdvice has once again teamed up with the Ballistic Case Company in order to offer you a chance to win an SG Maxx case ($49.99) for iPhone 4 and iPhone 4S.

Constructed of shock absorbent polymer and silicone as well as hard polycarbonate layers, the Shell Gel Maxx is able to shield your iPhone from some of the most brutal situations it may become involved in. The specific design consists of extra thick “Ballistic Corners,” port and button covers, and a rigid screen protector.

Beyond providing additional shock absorption, the size and shape of the Ballistic Corners offer increased screen protection. How? When laid, dropped, or slid on a flat surface, most of the case doesn’t make contact. Therefore, your iPhone’s display nor the screen protector are likely to experience any kind of damage.

The SG Maxx is packaged with an optional belt clip, and available in several single or two-tone color schemes. For this giveaway, we’re not guaranteeing color preference, although, we’ll do our best to fulfill your desired choice.

To have a chance at winning one of three SG Maxx cases, leave a comment below telling us if you’d prefer a bold color like pink or something more subtle like black or blue before Oct. 14 at 11:59 p.m. PDT. Only one entry per person is allowed, and limited to residents of the United States and Canada. Please be sure to also check your junk email box.
