Identifying Certificates May be Possible With 3.1

According to iH8sn0w it is still possible to find out the IBSS and IBEC certificates from your iPhone 3GS, even if you accidentally upgraded to OS 3.1. The IBSS and IBEC certificates are important (even essential) for the downgrade to OS 3.0. They are probably necessary in any jailbreak of OS 3.1 when it becomes available. Who is in possession of an iPhone 2G, iPhone 3G or iPhone with 3GS OS 3.0/3.0.1 should not follow these steps, they are only for the iPhone 3GS with OS 3.1.

Again, the following steps are for 3GS iPhone owners who accidentally upgraded to OS 3.1 and still have to find out their certificates. To find the certificates enter the following steps:

1. Identify the ECID of your iPhone 3GS.
2. Go to purplera1n.com, paste the ECID in the black input field under the correct logo (Windows or Mac) and press Enter. Note: This only works in Safari or Firefox, not Internet Explorer! Download the file that appears.
3. Send the file by email to ih8sn0wydaz@gmail.com
4. You should get a reply from this addresswith three certificate files.

These three files should make it possible to downgrade to OS 3.0. Saurik is busy making a down-grader, but has posted on twitter that he may start collecting certificate files from iPhone 3G[S]‘s running 3.1 within the next week. On the subject of a jailbreak for  OS 3.1: both the iPhone Dev Team and the Chronic Dev Team are busy, so it shouldn’t be too long until we see a release.
