Four years ago it started all: Apple released iPhone SDK 1.2b1 to the developer community on March 6th, 2008 and I did my first steps in iOS programming, too.
Nearly exactly 4 years after releasing the first SDK to its developers the App Store has reached 25 billion downloads on March 5th, 2012. Incredible!
And tomorrow on March 7th, 2012 Apple will release a new iPad together with iOS 5.1 – and maybe one more thing.
