Do you really need an iPhone 3G? We give you 5 reasons it’s the world’s best cell phone—and 5 reasons to wait to buy one or just keep rocking your 2G iPhone.

We admit it—after hearing Steve Jobs’s keynote at the Worldwide Developers Conference on June 9, we all wanted an iPhone 3G. Badly. There’s plenty to like about the iPhone’s second coming, but we wouldn’t be doing our jobs if we didn’t show you both sides of Apple’s newest smartphone, the good and the bad. In fact, the original working title of this article was “10 Reasons You Need an iPhone Now,” but in researching the story, we couldn’t look past the device’s clear downsides.

So in the spirit of the proverbial angel and devil that sit on either shoulder when you’re weighing a decision, we present both the good and the bad news about the iPhone 3G, so you can you make the most informed choice possible.

Perhaps the greatest part about the new AirPort Express is simply that Apple brought back the AirPort Express—the previous edition had all but disappeared from store shelves, and Internet message boards buzzed with worry that Apple was discontinuing it altogether. Luckily, those fears were unfounded: The new AirPort Express does everything the old model can, and it features the fastest Wi-Fi standard (802.11n) and ProxySTA, which acts as a bridge between wireless and Ethernet networks without requiring you to set up a Wireless Distribution System (WDS).

Holding down the Option key will reveal several hidden options to choose from in your AirPort Utility’s Radio Mode pop-up menu.

We had an AirPort Extreme wireless network that our HP LaserJet 1022nw was wirelessly connected to, and it was working fine until we switched to a Time Capsule as our wireless router. Now our printer can no longer see our wireless network in its SSID list, and when we manually type in the SSID information and WPA password information, it still can’t connect.

As of press time, there’s an incompatibility between some HP wireless printers and Apple’s implementation of the 802.11n wireless protocol built into the Time Capsule’s firmware (currently at version 7.3.1). By the time you read this, a Time Capsule firmware update should be available.

In the meantime, go into your AirPort Utility (located in Applications/Utilities), connect to your Time Capsule, click the AirPort button at the top, select the Wireless tab, and then hold down the Option key while you click the pop-up menu for Radio Mode. This will reveal several hidden options, including the one that you want: 802.11b/g compatible. Choosing this option will result in speed degradation on a network of all 802.11n devices, but it will enable your HP printer to see your wireless network once again.

Whether you’re packing for a business trip thousands of miles away, or you just want to get out of the house for a few hours, sometimes you need to take your Mac on the road. While it’s debatable whether “getting there is half the fun,” keeping your MacBook (and your workflow) running smoothly, both in transit and when you arrive, is an absolute must. And we hate to break it to you, but with a more-mobile Mac comes increased responsibility—like making sure your precious ’Book doesn’t get stolen, broken, or disconnected from the world. We’ve got the latest tricks for keeping your precious cargo safe, secure, and connected—and some advice for coping with accidents you can’t avoid.

We take the wraps off of Apple's new wireless access point. Come see the pictures!
