In as much as the iPhone 4 has drawn criticism, it does sport some nifty new technologies.

Among this is its new gyroscope, which could find its way into a future revision of the iPad.

Per InformationWeek, UBMTechInsights took a look inside Apple’s new iPhone 4 and found it was made by STMicroelectronics. The three-axis MEMS gyroscope is made by the same company that produces the accelerometer found both the iPhone and iPad.

Steve Bitton, senior analyst with TechInsights, noted that there is an empty slot on the iPad motherboard, perfectly sized to fit the gyroscope found in the iPhone 4. It is also located next to the accelerometer, and within proximity of the application processor.

The discovery suggests that Apple originally planned to have a gyroscope in the iPad, released in April in the U.S., but ultimately decided to leave the sensor out of the first-generation hardware.

But the pin out on the iPad motherboard doesn’t match the STMicroelectronics gyroscope found in the iPhone 4 — instead, Bitton said, it resembles a competing three-axis sensor made by InvenSense.

“When Apple’s iPad first came out, the InvenSense gyro was the only three-axis digital gyro on the market, so Apple may have designed its board with that component in mind,” the report said. “Indeed, Apple may have included it in the iPad initially, but may have ultimately decided against using it in either device.”

The cool cats at iFixit have also conducted a closer look at the iPhone 4 gyroscope, with the help of Chipworks. It also revealed that the gyroscope is made by STMicroelectronics, labeled AGD1 2022 FP6AQ. The microelectromechanical system (MEMS) integrates electronic and mechanical components at a very small scale to measure the orientation of the device.

X-ray photos of the gyroscope found that it is nearly identifcal to the off-the-shelf STMicroelectronics L3G4200D model. It includes a “proof mass” that is displaced in X, Y and Z directions by Coriolis forces when a user rotates the phone. Another die found inside converts those capacitive signals into a digital form that can be interpreted by the iPhone 4.

The gyroscope allows for far more precise movements with the device. One of the first App Store offerings to demonstrate this capability is Eliminate:GunRange, a US$0.99 title from ngmoco, Inc. The software allows users to conduct virtual target practice by aiming their onscreen gun with precise movements of the device, something that is only capable with the gyroscope found in the iPhone 4.

Apple releases mobile configuration profile update for iOS 4 Exchange ActiveSync bug

Apple has issued a configuration profile that addresses an issue in iOS 4 that may cause sync problems with Microsoft Exchange or Google Mail and Calendar.

Per AppleInsider, the company notes that “immediately after updating to iOS 4, some users may notice that Exchange ActiveSync Mail, Contacts, or Calendars do not sync, or sync very slowly. In addition, some Exchange Server administrators may notice their servers running slowly.”

The issue, according to a report by the site , is that iOS 4 sets a low 30 second default timeout for server requests that can overwhelm the server.

Apple has published a mobile configuration update file that administrators can distribute to iPhones and iPod touch users running iOS 4. The configuration update can also be downloaded directly to the device from Mobile Safari, using a link Apple provides.

Once installed and the device is restarted, the configuration update sets the timeout to 240 seconds, a change that has proven to fix sync issues for most users.

If you’ve seen this issue on your end, please let us know.

Late Wednesday, Apple released updated sets of Snow Leopard drivers for Hewlett-Packard and Epson printers and scanners.

Per Macworld, the first is version 2.4 of the Epson drivers, which comes in a package listed on Apple’s download page at a whopping 737MB; Epson Printer Drivers 2.4 provides updated compatibility between Mac OS X 10.6 or later and dozens of scanners and printers made by Epson.

On the HP side, the update, dubbed version number 2.4.1, is listed at a significantly smaller 388MB for the full download.) HP Printer Drivers 2.4.1 requires OS X 10.6.1 or higher in order to function and provides support for both printers and scanners made by Hewlett-Packard.

Both updates can be installed through the Software Update built into Mac OS X, or obtained directly from Apple’s Website for Support Downloads.
