You can not, it does not have the "phone" hardware in it.
yes it can
Not really, as the iPhone has a larger body than the iPod touch. It may be possible to put something else into the case as well as the iPod to make it fit.
yes.
Yes, all of them. However, some Iphone apps will not work with the ipod touch, so be sure to check when in the app store.
Many apps will work on the iPhone, iPad and iPod Touch. Some are written just for the iPad while others only work on the iPhone and iPod Touch. Under the title in the App Store it will specify which devices the app will work on.
sorry no, iPod has to be connected to WiFi for it to work
iPhone Apps, including games, work only on iPhone, iPod Touch and some work on the iPad.
For the iPod Touch 4: If the ipod touch's owner has the iphone owner's number, they can add it to 'contacts' and press 'facetime' and it should work. If the iphone owner has the ipod touch owner's email address, they can add it into 'contacts' and press 'facetime' and it should work.
yess it does
yes, ipod and iphone are the same device differing only in cellular capability and storage space.
No, the apps for iPad are much bigger rather than compressed like the iPod touch apps. For example, just as you would enlarge and slightly distort an iPod touch app on an iPad, you would have to compress and make smaller an iPad app for the iPod touch witch is virtually impossible
Dont know of this app is for iPod but it does Work on an iPhone 4s. It is called geosociety. It does crash very rarely. All you have to do is save it,
