Some you can get on both your iPhone and iPod Touch, but some are strictly for the iPhone. It will say if it's for both or one when you view the information for the app.
they are two different things! an itouch is basically everything that the iphone is without the phone. you can also install most of the apps that you can on an iphone on an itouch
Yes. They both have the same screen sizes and can both use the same apps.
You download the app and then sync the itouch or iphone to your computer. Warning: You can not download apps on anything but an itouch or iphone.
apps from an itouch, iphone, or ipad can very. check the app store to see all the apps
the iphone also has 3g capability's allowing you to browse the internet or use web apps anywhere the itouch needs to be on a wifi network to do any of that
Yes. Yes they do. But apps with location services won't be able to find your location.
Yes. Mainly except for the apps which require a camera. It is said to be a 3rd generation itouch coming fall 2009 with a camera though.
On the app store you have a very large number of free apps alongside paying apps. The same price is applied wether on iPhone or iPod Touch

im sorry but apps are only for iphone and itouch
iPhone and iPod touch games (or other apps) are never compatible with an iPod nano.
You would use it as an iTouch, all apps and settings just no phone or text.
