i would like to downgrade my iPhone 3G(jailbroken4.2.1) from ios 4.2.1. to 3.1.3.

What i will be missing?

Hope i can play all the games and use all the latest apps after downgrade.

Please help i want my iPhone to be faster. I use calendar a lot and it takes lots of time to open and edit it. My spotlight search is all off.Still its very slow. I want to downgrade.

Yeah, downgrade is actually your only one option here. However, there are many apps from the app store which got updated to iOS 4 so yes, you might miss some apps, specialy games.

I do not have an iOS 3, so i can say if those games will work on iOS 3, what i know is that most of those games have been upgrade to be fully compatible with iOS 4 ans so far as you are going to download them from the app store, it will return you a message saying that your iOS is not compatible.
As for downgrading your iOS from 4 to 4, i will ask to know if you haved saved shsh of iOS 3 before? And maybe apple doesn't sign those old iOS so you might just plug your phone to your itunes and clic "upgrade" button in the summary tab and see if it will advice you with the latest iOS available for your device. If not then you can download iOS 3 off internet and restore it manually.
