iPhone Firmware

Just in case you haven't heard, Apple announced a little product called the iPad 2 earlier today. Also discussed in the talk was a listing of the new features and software coming to iOS devices with firmware version 4.3. This operating system will be released on the iPad 2 shipping date, currently scheduled for Friday March 11, 2011.

So what comes with the iOS 4.3 update for iPhone owners? Mostly improvements to current features, such as a speed boost for the Safari web browser. Apple has implemented the Nitro JavaScript engine, which should make Safari twice as fast as the current iOS 4.2 browser.

Italian hacker Zibri has published a code snippet on his blog that points to a Qualcomm-sourced baseband chip in the next generation iPhone. The code in question showed up in iTunes, and hints that Qualcomm will replace Infineon as the source for iPhone 5 baseband chips.

Of course, Qualcomm is the originator of CDMA technology, and this code may just be in place for the Verizon CDMA iPhone. Zibri believes this is not the case, and several other sources have made it clear that Apple may be making the move to Qualcomm basebands across its mobile product line.

Some AT&T iPhone customers were shocked to see that the Verizon iPhone includes a Wi-Fi hotspot for up to five devices. Now that Apple has released the latest developer beta of iOS 4.3, it looks like all iPhones will be getting the feature. According to a report in BGR, Personal Hotspot is listed right under Wi-Fi under the Settings menu.

AT&T has not stated whether or not they plan to support the feature. For its part, Verizon hasn't mentioned data plan pricing yet, or whether or not tethering will cost extra. The app featured on the Verizon iPhone is actually native to iOS 4.2.5, the firmware running on the Verizon iPhone.

Some iPhone owners who jumped to install the iOS 4.2 firmware update yesterday were greeted with an unwelcome surprise. Media including music, audio books, podcasts and videos disappear after the update is complete. iTunes still displays the storage space occupied by the media files, but they are nowhere to be found on the iPhone.

Opening the iPod app simply says "No Content" and re-syncing with iTunes does not bring back the media library! Apparently something was overlooked by Apple, but lucky for iPhone owners the bug fix is quick and easy. Your music files are hidden but still stored on the device. Don't restore your iPhone or take drastic measures, just follow these simple steps:
