I personally think it's a bad idea, especially as a sticky at the top of the regular Marketplace. I didn't notice that there were that many iPhone threads in comparison to others. I thought it was fine all together.
(A small gripe is that I'm not really looking to buy an iPhone but every time I check the Marketplace now, the first thing I see is "iPhone Marketplace" and I have to actually scroll to see new posts)
