It depends on what app you are buying. If you look on the right hand side it says if its capable with iphone and/or iPod touch(but I think that all ipod touch apps can be played on an iphone but im not 100% sure)
The difference between the Iphone 4 and the iPod Touch is that the iPhone is techincally a iPod, but with phoning capabilities. Also, the iPhone 4 can use FaceTime, a app that use video calling. Also, the newest iPod has FaceTime too. So, both the iPhone and the iPod are both the same.
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.
yes, if it is an ipod touch and you both have iOS 5 or are using an app like textfree
almost every app made for iphone works on the ipod touch
go to the app store on your Ipod or Ipad and Iphone

the best way is to use the find my iphone app
Sorry, your gonna have to jailbreak your iPod or iPhone. Then you can get your app from cydia
No, Stick RPG has not been developed as an app for use on the iPhone/iPod Touch.
The Facebook iPod Touch/iPhone app can be downloaded from the iTunes App Store.
No, but the latest iPhone does...
well, you can only get them on iphone and ipod touch. to get them for your iphone or ipod touch, go to the app store on it and search the app you want. some apps are free. just touch the app you want and then touch download. if that doesnt work, use a cord to plug it into a computer with itunes then click the app store and do the same thing you would do on your iphone or ipod touch from there.
