Article cleary states which Android phone was used in the test but doesnt state which iPhone was used. It just says iphone 4.2 and iphone 4.3. Does that mean a iphone 3g on 4.2 and a 3gs on ios 4.3?
The study was done primarily on iPhone 4 and Google Nexus S.

"We used iPhone 4 for the iPhone measurements, and Google Nexus S for Android 2.3 measurements. For our Android 2.2 measurements we chose the Samsung Galaxy S, since it has almost identical hardware to the Nexus S, making the OS the primary difference."
