Wow! It was just less than 3 months ago since Apple sold its 1 billionth application, well, after a little over a year, Apple continues to sell more and more each day. Half a billion applications in just 3 months is insane!

This can be attributed to the new iPhone 3G S and its record sales. AT&T is reporting that the iPhone 3G S is the biggest selling phone they have ever had, in proportion to how many units were sold in such a small amount of time.

Now this is impressive, but possibly, this number may not be as impressive. I have not recieved clarification on whether or not this includes app updates. If so, 1.5 billion shouldn’t be too unexpected. I have downloaded over 300 app updates since iPhone OS 3.0 GM was seeded to developers back on June 8th. (Yes, I have a ton of apps, but I only sync about 250 of them.)

Well, either way, congratulations Apple, you are half way to your second billion.
