A whopping 100,000 apps are in the iPhone app store, just waiting for you to download. I’m not sure what percentage of them are free or how many of them are porny, although I can tell you that x-rated sites do seem to pop up everytime I’m searching through the list of top 50 free apps in various categories. Like the web itself, the world of apps is always in need of good curation. To help weed out the dreck, and zoom in on some good stuff, Mashable recently aggregated its reviews of 700 apps in a range of categories. Check out their impressive list of lists here. And please, if you stumble upon any truly terrific apps (especially freebies), spread the good news right here.
