How to downlod app iPhone 3G?

Go to whatever app you want & download. If it is not compatible then there's nothing you could do except get a 3GS or later model.

If you mean how to download apps for your iphone 3g than this should help.

your iphone has an app called "App Store" hit on that,(assuming you are already registered & signed in) you are now in the world of apps. You can download, search or browse apps according to categories. Some apps are free and some needs to be purchased.

Hope this answers your question.
