With iOS 4, Apple introduced iAd program so that developers can generate some revenues whilst keeping their apps free in the iTunes App Store. While the ads delivered by iAd are interactive and all, they are still of annoyance for most users. And so if you like your apps ads free, you can disable them all using a free app called iAdKiller for jailbroken iPhones and iPod touches.
Earning through paid apps for iPhone developers is not new, but earning $1400 USD in a single day through a free app in App Store is nothing less than hitting the jackpot. Jason Ting, a US based iPhone developer shared data on his revenues made using newly launched Apple iAd program. The data showed that he made $1400 on the first day alone for a iPhone 4 utility app that was approved, and released by Apple only yesterday. More astonishing was the astounding $150 eCPM which he got for his app from iAd program.
