No, and I think the odds against seeing these released to the market are increasing with time.

From the Magpul web site on 13 April 2010:

iPhone Case Release Delayed

As some of you know, Magpul announced the iPhone Field Case last January at the 2010 SHOT Show, with a product release scheduled for late February. Unfortunately, the current Field Case fit and finish are not representative of the quality and value that customers have come to expect from Magpul equipment. As a result, Magpul has chosen to delay its release in order to address these issues.
Ever since the company was founded in 1999, speed and efficiency in product development have been top priorities, but they will always remain secondary to the quality and performance for which Magpul is known. Delays such as these are understandably frustrating, but are sometimes necessary to avoid betraying the brand, and more importantly, the customers’ trust in Magpul products. More information and release dates will be posted as they become available.
Add to this the fact that the iPhone 4G has just been announced, and it just seems that the incentive to put the 3G cases into production is pretty much depleted. Magpul may surprise us yet, but I've long since given up on the idea that I'll be seeing a 3G case anytime soon.
