Tests carried out on a 2008 iPhone 3G running Apple’s iOS 4.2 GM seed revealed much faster performance compared to iOS 4.0 and iOS 4.0.1, suggesting the Mac maker has finally nailed down what was slowing the older-generation handset.

Facing countless complaints from customers worldwide, as well as a lawsuit seeking class action status in California, Apple appears to have finally resolved the issues leading to slow performance of iPhone 3G handsets upgraded to versions 4.0 and newer of the iOS mobile operating system.

iOS 4.2 seems to be the answer to these problems, according to a test carried out by the folks at TiPB, a blog focused on iDevices.

The video embedded below shows a comparison between iOS 3.1.3 - the latest of 3.x updates for iPhone and iPod touch devices, and iOS 4.2 - the newest version of Apple’s mobile operating system scheduled to launch publicly this month.

Needless to point out, the iPhone 3G is quite noticeably snappier running the iOS 4.2 GM seed handed to developers last week, compared to earlier tests carried out on 3G iPhones running iOS 4.0, iOS 4.0.1, and iOS 4.1.

TIPb outlines that the iOS 4.2 GM seed should be binary-identical to the final release.

In all senses, this means that the final shipping version of the software should do a similarly good job at ironing out all the bugs that kept the phone from responding accurately to user input.

Apple is yet to ship the new software, although the iOS 4.2 IPSW file is expected to arrive via iTunes momentarily.

Reports indicate that Apple is planning to launch the update this week, with various sources oscillating between November 9th and November 12th as the release date.

Apple is believed to plan a simultaneous shipping of iOS 4.2 and Mac OS X 10.6.5, two updates that have dependencies on one another.

Also worth noting is that the iOS 4.2 IPSW will be applicable to iPads, in addition to iPhones and iPod touches, delivering multitasking, application folders, Game Center, iAds, and more for the first time to the Apple tablet.
