IOS 4.2.1 Released this morning – Reports of Bugs Already Surfacing

Jailbreak Software Pic #100 - Spanish iPhoneIOS 4.2.1 Released this morning – Reports of Bugs Already Surfacing

Hey guys – some late breaking news about the new iOS that was released this morning. Apparently, when you update to iOS 4.2.1, your iPhone music does a disappearing act.

If this happens to you, though, don’t stress too much, because there is a pretty easy fix available. Also – in related news, alert hackers have already released jailbreak software for the new update. (Remember that this is legal under the latest ruling).

Easy fix for disappearing music on iPhone with iOS 4.2.1. upgrade

When iOS 4.2.1 was released on Monday (11/23), users almost immediately started having issues with music appearing to be erased from their iPhones. In a thread on, however, in the discussion forums, it was discovered later in the day that the music was not actually being erased, but rather just being hidden.

A user on the forum who goes by the moniker “slouchsock8” posted the following fix:

  1. Connect your iPhone to iTunes via USB cord
  2. Play a song through iTunes, but on the iPhone itself
  3. Re-sync the phone
  4. On the phone, open up the iPod application and rebuild the library

The update that was published this morning was released as 4.2, but technically is 4.2.1. The actual 4.2 was a beta that was released only to programmers and developers earlier in the month. However, Wi-Fi problems forced Apple Corporation to take the iOS into .1 status before they pushed it into wide release.

“Tethered jailbreak” for iOS 4.2 released early in the day, with related Jailbreak Software this afternoon

The greyhat dev community released a software jailbreak for today’s iOS nearly as soon as the update came out. (Jailbreaking refers to hacking the iOS, usually with the assistance of jailbreak software, so that end users can run code and applications that has not been approved by Apple.)

A group of hackers that has become very well known in certain circles (the iPhone Dev-Team) had an update to their unlock procedure out by 4pm today. They’re calling it “redsn0w” (better than yellow snow I guess), version 0.9.6b4. There are version out for Windows, as well as several flavours of Mac OS.

For the time being, the jailbreak is “tethered”, which may disappoint some advanced users. This applies to users with newer devices including newer 3GS models, any flavour of iPhone 4, the newest iPod touches, and all iPads. This means that in order to jailbreak these devices, the user will need to hook their unit up to a computer (Windows or Mac) via USB cable and re-do the jailbreak every time they restart their device. (So if this is you – do yourself a favor and keep your device charged!)

If you have the iPhone 3G, older 3GS models, or older gen iPods touches, then you will be able to do an untethered jailbreak.

Apple Corp. and the grey and black hat dev communities have been playing this “cat and mouse” game for the last several years. As soon as Apple plugs a security hole in the software, the hacking community finds a way to exploit a different one. Jailbreaking, through the widespread use of jailbreak software, has allowed owners of Apple devices to do things with them that Apple does not allow. For example, creating custom skins and themes, having multiple apps running at once, Wi-Fi tethering, and FaceTime.

The Apple company’s biggest concern seems to be that jailbreaking allows people to download software for free from the App store. They also complain that jailbreaking may leave the device open to hackers who want to steal personal information.

At this blog, though, I always say that the benefits outweight the drawbacks, and I recommend jailbreaking to any owner of an iPhone or other Apple device. Just keep in mind that although jailbreaking is now legal, digital piracy is not, so use your heads, ok?
