A timely snapshot
The Line2 app is a carbon copy, a visual clone, of the iPhone’s own phone software. The dialing pad, your iPhone Contacts list, your recent calls list and visual voice mail all look just like the iPhone’s.
(Let’s pause for a moment here to blink, dumbfounded, at that point. Apple’s rules prohibit App Store programs that look or work too much like the iPhone’s own built-in apps. For example, Apple rejected the Google Voice app because, as Apple explained to the Federal Communications Commission, it works “by replacing the iPhone’s core mobile telephone functionality and Apple user interface with its own user interface for telephone calls.” That is exactly what Line2 does. Oh well—the Jobs works in mysterious ways.)
