Today it was announced that the iPhone has hit the one million sales mark in just 74 days. The timing then could not be better for Scott Kelby and Terry White’s third party guide to making the most from this much ballyhooed device. Besides all the information included in the official Apple pdf manual for the device, the authors give a host of inside tips (called, cleverly enough, iTips) to go beyond the official manual into some of the more obscure workarounds that they quickly came up with. In offering more than the official 124 page version of the manual, Kelby and White, both longtime computer, software and gadget speakers and writers, have tried, successfully to come up with every imaginable angle on this very useful device. Whether you are interested in playing music, showing photos or movies, interfacing with the iTunes store, You Tube or Google maps, not to mention it’s incredible seamless user interface with a broad array of specific Mac applications (Safari, Mac Mail, Address Book, etc.) or even making phone calls, ‘The iPhone Book’ will go a long way to insuring you are getting the maximum value out of this year’s must have device - no matter what price you paid for it. - Tim Devine
