Yes, you can facetime from an iphone 4 or a 4th generation iPod Touch (the newest iPod touch that Apple has released) to a mac
Yes, FaceTime is free.
no facetime is free!
because there are a lot more ipod touch apps than the regular ipod games and apple doesnt make all the apps but they have to put more effort into the ipod games than the ipod touch/iphone apps.
Nope. If the person you are calling also has FaceTime, it I completely free :]
Yes, you can... But apps aren't on the Apple Store, they are on the App Store
Yes, it's free.
Only the iPod Touch will run apps. The iPod Nano will not run apps.
Yes. And that's how you can get back an app for free if you removed it from your iPhone and iPod Touch.
Go to App Store and find free apps... You go to an Apple Store or apple.com (or .ca) and buy one there.
There are free apps, and as long as you get the apps that are supposed to be free for free, then it is legal. If you get the apps you are supposed to pay for free by jailbreaking the iPod Touch, it is illegal.
No. FaceTime costs $0.99 on the Mac App Store, and is built in to all iOS devices (iPhone, iPod touch, iPad) as of June 2010. FaceTime is not available on the iOS App Store.
