Apple Releases iOS 6.0.1 - Fixes Keyboard Artifacts, Other Bugs (Update: iOS 6.1 Beta 1 Released As Well)

Posted: 01 Nov 2012 10:58 AM PDT

This morning Apple pushed iOS 6.0.1 (10A525) live for iPads, iPod Touches, and iPhones that can run iOS 6.0. The update fixes a number of bugs that we noted in our review of the iPhone 5, including one which affected the keyboard and occasionally manifested itself with some rendering artifacts. In addition the update promises improved WiFi connectivity for BCM4334 based devices like the iPhone 5 and iPod Touch 5th generation on networks using WPA2 encryption. 

The actual changelog is below:

This update contains improvements and bug fixes, including:
  • Fixes a bug that prevents iPhone 5 from installing software updates wirelessly over the air
  • Fixes a bug where horizontal lines may be displayed across the keyboard
  • Fixes an issue that could cause camera flash to not go off
  • Improves reliability of iPhone 5 and iPod touch (5th generation) when connected to encrypted WPA2 Wi-Fi networks
  • Resolves an issue that prevents iPhone from using the cellular network in some instances
  • Consolidated the Use Cellular Data switch for iTunes Match
  • Fixes a Passcode Lock bug which sometimes allowed access to Passbook pass details from lock screen
  • Fixes a bug affecting Exchange meetings

Interestingly enough the iPhone 5 shipping software has a bug which prevents it from getting the over-the-air update without a standalone helper application. The result is that users updating the iPhone 5 have to go into Software Update, which then begins downloading the helper application. After that's installed, the OTA can download and install normally. The iOS Updater helper application then goes away after the OTA has been installed. 


There's also note of a change to improve iPhone cellular connectivity. I'm hoping this resolves some issues I've seen where the iPhone 5 will randomly show no carrier string until after airplane mode is toggled. Curiously enough baseband version for the iPhone 5 remains 1.01.00.

In addition Apple has released iOS 6.1 Beta 1 and Xcode 4.6 for developers. iOS 6 B1 appears to have some new functionality for MapKit, but not much more at this point. What a day for Apple updates!

Dell Latitude 6430u Brings Wilocity's 802.11ad WiGig Solution to Consumers

Posted: 01 Nov 2012 08:00 AM PDT

Wireless networking has been making rapid strides in the last decade. Starting with the 11 Mbps 802.11b in mid-1999, we now have more than 1 Gbps of wireless throughput with 802.11ac. Wi-Fi technologies have worked in the 2.4 GHz and 5 GHz bands till now. Many companies have tried to use the 60 GHz band for communication (mainy wireless video). WiGig is a 60 GHz technology aimed at wireless data transfer similar to Wi-Fi. However, operation in the 60 GHz band implies that it is meant to be more of a in-room technology. WiGig is being standardized under the 802.11ad task group.

Wilocity is one of the leading WiGig silicon vendors. They have been demonstrating their solution in various trade shows over the last year or so. In fact, we had covered their docking solutions at the 2012 CES as well as Computex 2012.

One of the main challenges for WiGig was to gain market traction. Something had to make a business case for WiGig and Intel's Ultrabook initiative emerged as the perfect opportunity. Pitching a standalone 60 GHz solution wasn't going to cut. So, Wilocity teamed up with Wi-Fi vendors to present a tri-band solution (2.4 GHz, 5 GHz and 60 GHz) to the notebook manufacturers. Qualcomm-Atheros was one of their first partners and they also teamed up with Marvell recently. As you can see from our earlier coverage, Wilocity pitches WiGig based docking stations for Ultrabooks. With the Windows 8 product launches, we are seeing the first such device making its way into the hands of the consumers.

The Dell Latitude 6430u Enterprise Ultrabook (the first Ultrabook in the Latitude line) incorporates the Wilocity / Qualcomm-Atheros tri-band chipset for the wireless docking and networking capabilities. The Dell WiGig-enabled docking station (also powered by Wilocity, obviously) enables the Ultrabook to wirelessly connected with a number of I/O devices such as external GPUs, storage, peripherals and expansion slots. It is no wonder that Dell is the first to market with a WiGig solution, considering that they are one of the founding members of the WiGig Alliance.

Pricing for the Ultrabook (as well as the docking station) is not yet public, as both are expected to be B2B solutions. The response to the Ultrabook / dock will be interesting to watch, as it will be an indicator of when (and whether) the solution will become available to consumers directly.
