Your iPhone’s saved web apps or in-app browsers in the home screen seemed slower than Safari itself. Ars Technica has now confirmed that the pages or web apps loaded using these methods are not receiving the JavaScript boost added to Safari on iOS 4.3, which the site found is 2.5 times faster than Safari iOS 4.2. The problem is the apps is not having the necessary permissions to execute dynamically generated native code stored in writable memory, which basically leaves them running at the same speed they did in iOS 4.2. So, it has promoted some to speculate thats all a part of grand plan on Apple’s part to force developers to use full fledged apps instead of mobile apps, but what the Ars Technica told that could just as easily due to some technical problems.
