teve Jobs mentioned in his April 8, 2010 event that iOS 4 will be available for iPad soon as planned by Apple to boast multitasking, iAds and many other exciting features for this incredible device. However, he didn't mention the exact date for the availability of iOS 4.0 for the iPad back then.
The expected date for the release is November 2010. Apple is showcasing the iPad as the most profitable platform for those advertisers who want to board with iAds. The report revealing this says:
“Apple is telling marketers that the device considered most promising for advertisers — the iPad — won’t be on the iAd platform until November.”
iPad has already proven it's success with content showcasing so definitely it will do magic for all those magazine apps and advertisers.
