So in a couple of days the iPhone 3G is going to go on sale. Like many of you I am going to get this device as part of my duties as an intrepid reporter (and a shameless Apple-holic.) However, if you are rational, then you might want to read these reviews by the big three tech writers and their take on the iPhone 3G before you decide to hand over your credit card to the sales people.

• Walt Mossberg/WSJ: “I found it to be a more capable version of an already excellent device. And now that it’s open to third-party programs, the iPhone has a chance to become a true computing platform with wide versatility…if you can live with the higher service costs and the weaker battery life.”

• Edward Baig/USA Today: “With GPS newly added to the mix, this handheld marvel has no equal among consumer-oriented smart phones. While not everything on my wish list made it onto the new device, Apple has raised the bar with iPhone 3G. To which I offer an enthusiastic thumbs up.”

• David Pogue/NYTimes: “It’s not so much better that it turns all those original iPhones into has-beens. Indeed, the really big deal is the iPhone 2.0 software and the App Store, neither of which requires buying a new iPhone.”

I am sensing some hesitation on the part of the these reviewers. And now that you have read their reviews, are you still interested in buying the iPhone 3G.
