Apple has lashed out at Blaze Software, the company behind the test, saying: "Their testing is flawed. They didn't actually test the Safari browser on the iPhone. Instead they only tested their own proprietary app, which uses an embedded Web viewer that doesn't actually take advantage of Safari's Web performance optimizations."
Blaze has updated its website in response to Apple's rebuttal, kind of admitting it made a mistake, but also attacking Apple for crippling iOS's embedded Web viewer.
By not updating the embedded Web viewer, developers are claiming that Apple is intentionally stymying the performance -- and thus adoption -- of Web apps on the iOS platform. It could simply be that Apple didn't get around to updating the embedded Web viewer in time for iOS 4.3's release, though.
