Apple has included a major amount of fixes and tweaks in iOS 4.2.1 â€” here’s a look at a few at what’s new in Safari that will entice Web Developers and how Apple is working to squash a sluggish user experience.
Better RAM Management â€” Apps Faster Over Beta Versions
A large concern iOS users have with every new major release is how their iPhone, iPad or iPod Touch will handle it. IOS 4.0 caused problems for iPhone 3G owners as they were plagued with slow launching Apps which Â restarts only solved some of the time. These issues can be attributed to the lack of RAM in the iPhone 3G â€”128 MB compared to the 256MB available in the iPad, iPod Touch and iPhone 3GS.
Apple has kept the complaints of iPhone 3G users in mind as iOS 4.X builds have continually focused on better RAM optimization. The Italian site IPad Device put together a breakdown of how Apple has changed RAM allocation between some of its iOS Apps.

Safari has also been updated to take advantage of more HTML5 features and adds support for the Gyroscope and Accelerometer according to Mobile Web Programming via The iPhone Blog.
