Appl'e now requires app publishers who allow outside app purchases, make their content avaliable through Apple app store too.

Ars writes "Apple has responded to the furor over its supposed App Store policy changes that many believe could affect the popular Kindle, Nook, and Sony Reader apps. The company claims it has not changed any of its guidelines given to developers, but it indirectly confirms that accessing content purchased elsewhere could be a no-no if that content isn't also available to be purchased through Apple's own system.

"We have not changed our developer terms or guidelines," Apple spokesperson Trudy Muller told Ars. "We are now requiring that if an app offers customers the ability to purchase books outside of the app, that the same option is also available to customers from within the app with in-app purchase.""

Chatter began when Apple rejected Sony's Reader app for iPhone. Sony wrote

"We would like to update everyone on the status of our Reader™ for iPhone® mobile application. We created an app that we’re very excited about, which includes all the features you’ve come to expect from a mobile reading application – including access to your existing collection, synching with your Reader Daily Edition™ and purchasing new content as is possible on other mobile platforms.

Unfortunately, with little notice, Apple changed the way it enforces its rules and this will prevent the current version of the Reader™ for iPhone® from being available in the app store. We opened a dialog with Apple to see if we can come up with an equitable resolution but reached an impasse at this time. We’re exploring other avenues to bring the Reader experience to Apple mobile devices. We know that many of you are eagerly awaiting the application and we appreciate your continued patience."

According to source below, minimum ad budged for Appl'es iAd Platform is $1.000.000 in the U.S and £600.000 in the U.K. 

So unless you are a very big company and wan't to target Apple products only prices are way to high.

Well, Apple made headlines again! An iPhone developer made $1,400 from adverts on his free flashlight app for iPhone 4 in it's first day! Here is the proof

It is of course no where near sustainable and novelty of iAd plays big role in this income but still  $1,400 in one day is huge money to make from adverts! I know tens of mobile web developers that would be happy with $5 income a day from their mobile site!

iAd gives %60 of  income from an advert to the developer so from a $2.00 CPC advert publisher gets $1.2. On the other side you earn between $0.01 - $0.07 per click from other mobile advertising companies such as Admob, Inmobi, Mojiva, Buzzcity, AdModa.

 As much as I am against this App hype and Apple's Walled garden approach. I can't help my self but envy!
