The all time famous Redsn0w 0.9.5 is used to Jailbreak iPhone 3G 4.0 Beta firmware. However, if you are a user of iPhone 3GS, then you are facing some bad times as Redsn0w 0.9.5 currently only supports iPhone 3G. The current Jailbreak for OS 4.0 is in testing phase and to motivate the developers to get ready with their applications for the upcoming OS 4.0 as will be announced in WWDC 2010.
Till the time, Apple announces iPhone OS 4.0, don’t get your expectations high for jailbreak tools that will help you with iPhone 3GS 4.0. However, don’t think that it means you cant jailbreak at this moment! Beside the usual iPhone hackers, another unusual enthusiastic Kaatje has successfully jailbreaked iPhone 3GS 4.0 but alaas the process is not that simple as you are used to with the traditional developers.
However, the best part of Kaatje’s jailbreak technique is the retaining of iPhone 3GS baseband even after restoring to OS 4.0. Kaatje has managed to do this feat by creating custom OS 4.0 ipsw file and then restoring it on her test iPhone 3GS, thanks to P0sixjinja. Since the baseband is still 05.11.07 the phone is not locked, it can be downgraded back to 3.1.3.
According to her blog post,
“I accomplished this by patching asr, lockdownd, LLB, iBEC, IBSS, iBoot, kernelcache, MobileSafari, Services.plist, and fstab. The binaries were patched with IDA Pro and OxED and were then diffed against the original pwned files with bsdiff to create patch files. I then took the diff files and built a firmware bundle that I dropped into Pwnagetool and updated the cydia tree within Pwnagetool as well. Once this was done, I created a custom ipsw with Pwnagetool, unzipped it, applied a pwned LLB from a pwnagetool generated 3.1.3 ipsw, zipped it back up and restored to my device.”
Here are some of the screen shots as shared by Kaatje’s.
As you must be aware that OS 4.0 is proprietary code of Apple, there you won’t find custom iPhone OS 4.0 ipws anywhere till it is not released by Apple itself.
