iPhone VoIP Comes with Trade-Offs

[Graeme]

The iPhone has certainly been at the center of the news recently. Apple Inc. introduced the new iPhone 3G model and sold more than 1 million of the devices the first weekend that they were available. And through its online App Store, Apple for the first time began to offer third-party applications that can run on both new and earlier iPhone models (the latter requires users to upgrade to version 2.0 of the operating system). For many cost-conscious users, the most important iPhone apps will involve VoIP, which will let them avoid the high cost of calling overseas from a mobile phone. But as is the case with all mobile VoIP solutions, iPhone VoIP will come with trade-offs.
