No more iOS4 on iPhone 3G. I’m switching back to iOS 3.1.3
Update on stock iOS4 on iPhone 3G [The observation]
1. Battery Life, still bad and very bad.
2. Unresponsive keyboard, sluggish, very slow loading of iOS4 native apps such as Mail, iPod and Setting.
3. I give up Folder, iBooks and other features of iOS4. IPhone 3G just can’t handle iOS4 so well. Most probably, iOS4 is written based on iPhone 3G(s) and iPhone 4.
