When iPhone 3G users installed iOS 4.0, the result was an extreme slow down in performance. Simple tasks such as typing or just flicking through home screens caused major lags and a horrible user experience.
Upon release of iOS 4.1, iPhone 3G performance was improved but it was still not close to the pre-iOS 4.0 days.
With the impending launch of iOS 4.2 this month, TiPB decided to install the iOS 4.2 GM seed onto an iPhone 3G to see if performance had improved.
As seen in the associated video, iPhone 3G performance with iOS 4.2 seems to be dramatically improved! Apple has done all that they can to make the slower iPhone 3G really shine with iOS 4.2.
Almost all tasks run faster on iOS 4.2 such as scrolling, typing, and flicking through lists or home screens. For users with an iPhone 3G, iOS 4.2 is the firmware you’ve been waiting for!
