Would Blackberry's price minimum ensure a quality App Store?

Here's an interesting idea for the App Store. Gizmodo posts that the new Blackberry "App World" has set a minimum price on its apps, asking no less than $2.99 for whatever you buy in there. At first glance, that's pretty rough -- there are a lot of free apps on the App Store right now that we wouldn't pay 99 cents for, much less $2.99. But then again, Gizmodo is willing to at least suggest the benefit of the doubt: maybe it's done on purpose, to get us past the scourge of the many fart and other useless apps populating the App Store. Maybe if every app is sold for $3 or more, they'll end up all being worth that much, too.

But we have to agree with Gizmodo's conclusion, too: while it would be nice if every app on the store was worth more than $3, there are definitely a few apps out there that are worth having the lower (and free) prices for. And to add to that, it's hard to believe that, even at $3, every app would strive to live up to that price -- most likely what will happen is that you'll end up with just as much crap on the Blackberry's store, except that you'll be paying $2 more for it.

Still, it's an idea. If Apple did a little price tweaking, is it possible that they could ensure a little more quality to what shows up on the store? Or, in the case of the junk that's on there now, will we just end up with higher-priced junk?
