Is it only when you are using WIFI or when you are on 3G only? I know my iPad can make VOIP phone calls to other iPhone 4 holders
If that is the case, it's one of the sick reasons to get a iPad or a unactivated iPhone but only works with WIFI but again only to other iPad and Iphone users.
sun,
I have an ipod touch 4G also. And, it does
almost all the same things that an iphone can do except it doesn't have a built in GPS, compass or have 3G capability. Plus, the ipod touch battery doesn't quite last as long either; sort of sad. The app called, "talkatone" works with the ipod touch 3rd and 4th Gen. Sort of like you mentioned, voice over IP or 3G or wifi. There is a
slight lag in transmission but the clarity is reasonable and comparable to normal cell phone communication. Facetime works great and even pictures and videos aren't half bad. Apple makes great stuff and the iphone is no exception.
This iphone is awesome and yes, it's still activated:3G and AT&T wireless fires up; just no tethering. I will admit I'm going to be sad to see it turned off.
