VoIP App "Line2" now approved by Apple...after a 3 month wait.
It is true that Apple has approved this interesting app.
It is not true that it is VoIP, over 3G or otherwise. This app uses your AT&T minutes. Apple will approve these. They will approve VoIP that uses an alternate Internet connection, usually WiFi to an access point.
The applications that Apple is not approving are those that use VoIP over 3G. To the best of my knowledge they have rejected every application that attempts to do that.
Note that most IP applications, like VoIP, are connection agnostic. They do not know or care whether they are connected (at layer 2) via 3G or WiFi. AT&T cannot tell. That is why VoIP will work over 3G on jail broken iPhones. Only Apple can tell that an application is
both VoIP and connection agnostic. These are the ones that Apple rejects. Apple's only interest in doing this is to accommodate AT&T.
This is what the whole "network neutrality" argument is all about, whether a carrier should be able to discriminate among IP packets based upon use, content, origin, or destination. Both AT&T and Apple can argue that they are not discriminating, but the effect of their collusion is to discriminate.
Apple has also rejected other applications, like Google Voice and this one, that alter the basic phone application of the iPhone. At least to that extent, this approval is a break-through. The question for Apple is why Line2 and not Google Voice?
