About the Vu, the Tribune 's Eric Benderoff said, "Unlike with the iPhone, I needed to press firmly, and I often hit the wrong keys because the letters are squished together. ...More important, the haptics controls didn't work well for the other functions that the iPhone has made simple: scrolling through the content on your phone or surfing the Web. For instance, you can't use a finger swipe to move through pictures or, in what enthralls many iPhone owners, use two fingers to enlarge an image or Web page."

About the XV6900, Benderoff said, "Navigating those Web pages was a pain: Do I use my finger or the stylus? Neither worked well. There is no magic here. The functional XV6900 would be impressive if this were still 2006."

He concluded, "Perhaps the next few efforts at a touch-screen phone, including Sprint's Instinct, will provide the fun and function Apple got right in its first effort. So far, if someone asked me to suggest a cool touch phone, there's still only one worth buying."

So, there may be a spate of new touch-screen phones, but none comes close yet to Apple's.

My company uses Exchange for e-mail, calendars and contacts. My BlackBerry supports that, and I think iPhone should, too.

The only way to retrieve Exchange e-mail is when certain IMAP functionality is turned on from the Exchange side; whether this function is supported varies from IT shop to IT shop. Even if it is enabled, that doesn't mean that e-mail notification would be instantaneous, as is true for BlackBerries. The iPhone pulls e-mail after a set period of time, either manually, or every 15, 30 or 60 minutes. The shorter the interval, the more the battery drain.

Apple has shown a version of iPhone software that will support native Exchange support, with full push-email, -calendar and -contact management. Full integration directly into the Exchange server, without an intermediary machine and accompanying server license and software, means fewer points of failure and increased savings in hardware costs and license fees. These features are specifically meant to entice business users accustomed to partnering with RIM, but they aren't the only thing Apple has coming. It also plans on implementing global address lists, Cisco IPsec VPN, certificates and identities, WPA2/802.1x support, enforced security policies, device configuration for enterprise customers and remote wipe. All of this will come standard with the next software update, due sometime in June.

I don't like how Apple stops you from installing third-party applications. Fix it.

I don't have to. Apple's next software update should take care of this. When Apple showcased the iPhone SDK, it also showed off third-party application developments as a sneak peak of what's to come. It also introduced a new way to add software through its App Store that will be part of the next major update for the iPhone. That's when the floodgates for third-party applications will be unleashed.

There is some information on my iPhone that isn't syncing correctly, or maybe it's corrupt. How do I fix this?

Sometimes your iPhone can act up. It's an electronic device. Your best bet is to try holding down the power button on top until you are prompted with the virtual slider to shut down the phone. Once the iPhone is powered down, turn it back on. You're basically rebooting it.

If problems persist, you may need to re-sync your data. To do so, plug in the iPhone to your computer using the USB cable and launch iTunes, if it's not launched immediately. Select the iPhone in the iTunes sidebar and click on the Info tab. If you scroll down, there is an Advanced section that allows you to replace specific information during the next sync. The ability to reset data includes contact, calendar, mail accounts and bookmark information, and can easily be done by checking the appropriate data option and hitting the Sync or Apply button.
