A few days ago, Apple released iOS 4.3 beta 1 to developers. It appears iOS 4.3 will not be available for iPhone 3G and iPod touch 2G. Both devices are not listed on the iOS developer website.

This indicates that the final iOS built for iPhone 3G and iPod touch may be iOS 4.2.1. iPhone 3G has an older processor and has always been slow to run on iOS 4.x. There was a slight increased in speed and performance on iOS 4.2.1 but as the iOS becomes more sophisticated and complex, iPhone 3G will not be able to handle the any iOS beyond 4.2.1.

My Iphone 3G jailbroken and running IOS 4.2.1 can be extremely slow. Also wifi is weak and I need to be close to the wifi source. Any suggestions?
Should I downgrade to an IOS 3 version or IOS 4.1 or 4.0?
3.1.3 :)
Hmmmm I would loose multitasking then :o( ….. Is it true multitasking? Seems only like apps are loaded in memory. A game that I'm playing doesn't start from where I left it, when I switch back.
4.2.1 has it
