Testing has shown that the iPhone 3G’s performance is much improved under iOS 4.2 when we compare both iOS 3.0 and 4.2 (the gold master) running on an iPhone 3G.

Entering text into Apple’s Notes app was acceptably snappy. Browsing the Web was also noticeably improved, especially scrolling and load times (over Wi-Fi). Some pinch-and-zoom was a bit laggy, but definitely worlds better than iOS 4.0 on a 3G.

Apple was recently hit with a class action lawsuit from California iPhone 3G user Bianca Wofford, who claims that Apple “…knowingly and intentionally released what it called a system software ‘upgrade’ that, in fact, made hundreds of thousands of the Third Generation iPhones (sic) that were exclusively tethered to AT&T data plans ‘useless’ for their intended purpose.”
