iPhone 3G and 3GS users beware! Yes, that’s what iPhone Dev team is trying to say in their latest article about future proofing the iPhone 3GS jailbreak.
Earlier when Apple announced iPhone OS 3.1, there were some rumors of iPhone 3G and 3GS getting permanently locked. Many iPhone users updated their device to latest iPhone 3.1 firmware update and now they simply can’t use the facility of carrier unlock in the future.
If you’ve *only* updated iPhone to iPhone 3.1 firmware then there is a chance of using jailbreaking facility once again by using saurik’s “on file” server. You can read more about it here. But if your iPhone is locked with new firmware then there is no way to come back again. Even if you revert to iPhone 3.0 firmware, it will remain locked.
For those who have not updated iPhone 3G or iPhone 3GS to iPhone 3.1 firmware, they should redirect iTunes signing process through saurik’s “on file” server, which will help you secure the jailbreak process.
iPhone Dev team says -
We fully recommend redirecting your iTunes signing process through saurik’s “on file” server to future-proof your 3GS jailbreak through all future updates.
The iPhone 2G, iPod touch 1G and iPod touch 2G users can happily jailbreak their devices without any severe problems. In order to gain and retain the future jailbreaking, don’t install official iPhone firmware, you’ll have to use custom IPSW file. The iPhone Dev team will release PwnageTool for iPhone 3.1, which will create a custom firmware file for smooth jailbreaking process.
So, now just wait for further updates and do not use any new technique to jailbreak or unlock iPhone 3.1 firmware on your iPhone.
Update: PwnageTool 3.1 for iPhone OS 3.1 is now available.
