The iPhone Dev Team has just released Redsn0w 0.9.6b3 which brings support for iOS 4.2.1 GM firmware file. The highlight feature of this release is SSH and SSL support which will now allow you to install bundles and packages independent of Cydia, which is currently broken on 4.2.1.
I have just jailbroken my iPad on iOS 4.2.1 using PwnageTool bundles released by Johnny Franks. These bundles can be used to jailbreak the newly released iOS 4.2.1 GM on both iPad and iPod touch 4 with working Cydia !
iOS 4.2.1 was released yesterday for iPhone 4, 3GS, 3G, iPod touch 4G, 3G, 2G and iPad. Even though iOS 4.2.1 jailbreak is possible via Redsn0w 0.9.6b2, but Cydia is still broken which makes the jailbreak pointless for many. It also contains new baseband for all iOS devices which currently makes it impossible to unlock using existing version of Ultrasn0w. So if you upgraded to iOS 4.2.1 and now want to downgrade back to iOS 4.1 / 4.0.2 / 4.0.1, follow the instructions posted below to downgrade iOS 4.2 on iPhone 4, 3GS, 3G, iPod touch and iPad to iOS 4.1 / 4.0.x.
After releasing a revised version of iOS 4.2 GM for iPad to developers last week, Apple has now seeded iOS 4.2.1 GM for iPhones, iPad and iPod touches. This build is meant for developers only. Only members enrolled in the iPhone Developer Standard or Enterprise Program can access these bits of by signing into Apple Developer Connection.
The official Twitter blog has just announced full iOS 4.2 compatibility for iPad and iPhone clients, and official push notifications support for Direct Messages (DMs) and Mentions for Twitter for iPhone client.
New version of iREB for all iOS 4.1 devices is now available for download. You can use it to bypass 1604, 1603, 1602, 1601, 1600 error in iTunes during custom iOS 4.1 firmware restore which has been created using either Sn0wbreeze or PwnageTool.
Sn0wbreeze 2.1 for iOS 4.1 / 3.2.2 is now available for download. If any of the existing iOS 4.1 jailbreak tools didn’t work for you, you can give Sn0wbreeze 2.1 a try! For those of you who don’t know, like PwnageTool for Mac, Sn0wbreeze for Windows can be used to create custom firmware files for iOS 4.1 without the upgraded baseband so that you can unlock iOS 4.1 (05.13.04 baseband) with existing version of Ultrasn0w.
Apple has just released a second iOS 4.2 GM seed for iPad. This new Build 8C134b for iPad has been released in the wake of WiFi bug which we reported about yesterday.
The final version of iOS 4.2 was originally scheduled to drop sometime this week. We then heard about reports of it being released on Friday (Tomorrow), with iTunes 10.1 and Mac OS X 10.6.5 on this past Wednesday. While OS X 10.6.5 did drop on time, iTunes 10.1 didn’t.
Mac OS X 10.6.5 was supposed to bring AirPrint support for any printer connected to a Mac. Reportedly, Apple has removed AirPrint support from OS X in the final release of 10.6.5 due to some last minute patent issues.
