In iOS 5, Apple has fixed a long standing issue that prevented home screen web apps from running as fast as they would within Mobile Safari.
As it turns out, it was all an error. Blaze used their custom web app to run the test, and the version of Safari Apple allows web apps to use in iOS 4.3 had not yet been updated to Nitro. None the less, you’ll still occasionally hear Android fans chirping this dubious statistic to the heavens.
Well, no longer. iOS 5 finally rolls Nitro into Web.app. Now, web apps running from the homescreen will benefit from the same boost that web apps running under Safari enjoy. Good to know.
