Jailbreak iPhone 3GS : We know you are eagerly waiting for jailbreaking your iPhone 3GS with Firmware 3.1, last time Dev team released Pwnage tool for iPhone 2G, 3G and iPod touch 1G for 3.1 Firmware. Apple patched most of the holes that allowed the execution of Redsn0w and Purplera1n, but that doesn’t means Apple wins the Cat and Mouse game. ChronicDev (unofficial iPhone Dev team) has found a new exploit but will require additional time before being completed and released in the form of semi-automatic program. Now we have to wait and see who releases 3GS jailbreak first iPhone Dev team(Redsn0w) or ChronicDev (Purplera1n).
What is ECID, SHSH : Apple introduced new hardware and software security with iPhone 3GS, the biggest security is ECID, ECID is a unique chip ID and will be different for every iPhone. When iTunes starts the restore process, iTunes contact Apple servers to generate signatures just for your device. Saurik detailed the process in his words “ For any techno-geeks out there: Apple sends an XML “plist” formatted Property List to the server including base64 digests of hashes of parts of the file, as well as the chip/board identifiers that determine what kind of device it is, and finally the per-device ECID: the server then returns a plist of signatures. “
Thankfully Saurik already hacked this security for those who saved their SHSH earlier to 3.0,The process is very simple all you have to do is to add Saurik’s Server address to your system hosts file. This trick make iTunes thinks it is talking to Apple, it is talking to Cydia instead while the restoring process. Doing this will allow iTunes to access signatures already stored by Cydia’s “on file” feature.

- I Saved the ECID signature on 3.0.1 : you can always go back, restore the same firmware and run the jailbreak on this
- I Didn’t Saved the ECID signature on 3.0.1 : You must remain with the 3.0.1 update without until it is released on the 3.1 Jailbreak
- I updated to 3.1 but has saved the ECID via Cydia : You can go back to 3.0 and run the Jailbreak any time. To downgrade follow our guide for Downgrading iPhone 3GS from 3.1 to 3.0 with Cydia SHSH. However you aren’t eligible for Ultrasn0w anymore because your baseband is updated..
- I updated to 3.1 but didn’t saved the ECID via Cydia : Sorry to say but you can not do anything without Jailbreak and must remain locked until the release of the new tool with the exploits of Chronic Dev Team.
