MuscleNerd has confirmed over Twitter that, as they suspected, 2.2.1 does in fact break the "injection hole" that project yellowsn0w uses to modify the firmware to unlock the device for use on any carrier. He posted a video explaining the situation on Qik.
Software update version 2.2.1 (5H11a), is now available in iTunes. We haven't had time to check it out, and neither has the Dev Team. They suggest to anyone that wants to be able to hack their iPhone or iPod Touch in any way that you do not update until they have a chance to check it out, as there is a possibility it may break one of the exploits they use currently or will use in future hacks.
Mac users wanting to hack their iPhone or iPod touch should beware—The update Apple released today (10.5.6 for Mac OS X Leopard) has been found to keep your Mac from recognizing your iPhone in DFU mode, making it impossible to jailbreak and/or unlock it using PwnageTool or QuickPwn. If you intend to jailbreak or unlock your iPhone or iPod touch, we suggest waiting on the update until the Dev Team comes up with a solution. The Dev Team has been informed of the issue and we'll keep you updated as more information is available.
A new issue with the 2.2 software may cause some trouble for people with legitimately unlocked iPhone 3Gs. A few users in an Apple Discussions forum thread are claiming that the iPhones some of them purchased in an unlocked state are being re-locked by the 2.2 update.
Today is all about the new 2.2 software. While it does add a lot of cool new stuff, some users have reported a wide range of issues caused by the update, some more serious than others. Problems have ranged from internet connectivity and SIM card issues to applications going haywire or just not working at all.
The 2.2 Software Update for the iPhone (and one for the iPod touch too) was released late last night, and from what we've seen it looks pretty awesome (more on that to come), but those of you who are hoping to unlock your iPhone 3G should be cautious. The Dev Team warns on their blog that updating to 2.2 will seriously reduce your chances of being able to unlock that iPhone any time soon.

The iPhone Dev Team has updated their blog concerning the predicted 2.2 software update for the iPhone and iPod touch, reminding everyone that if you're concerned about being able to jailbreak, and especially unlock, your iPhone, then it is strongly suggested that you hold off on installing the update until they give the all clear.
According to Greek iPhone site iPhone Hellas, Apple will be releasing the next iPhone software update on November 21st. Included in the release are most of the features we've been expecting. iPhone Hellas believes we'll see minor changes to Safari, Google walking directions and public transit info, as well as some other minor tweaks and additions. There's still no word on push notifications or copy/paste and so we're not expecting either in this next release.
German iPhone site iPhone-Ticker.de stumbled upon an interesting find recently. It turns out that Apple has been tinkering with their iTunes Store servers in anticipation of the next software release, or at least that's what they think.
