Is IBSS, IBEC, and ECID still important?

[mwg3c]

I have a jailbroken 3GS and am planning on upgrading from 3.0.1 to 3.1.2. Do I still need my IBSS, IBEC, and ECID files to ensure future jailbreaking? Can I use the "iBEC_iBSS_Grabber" tool when I am restoring to the Custom 3.1.2 firmware?


I plan on following this tutorial to upgrade to the custom 3.1.2 firmware:

Anyone, anyone? Bueller??

Does anyone have an answer to this?

Save yourself the time. Just go into Cydia an allow it to save all that stuff for you.

Cydia only saves the ECID file, from what I understand. Do we still need to save the IBSS & IBEC files in order to allow future jailbreaks? Anyone up-to-date on this stuff?

You should be fine with what Cydia saves out. To this point the files have only been used for a signed/valid firmware, but if you point your hosts file to the Cydia servers instead, it will sign them with whatever ECID you have stored ( so far ).

Does anyone else have any thoughts?

So is the IBSS and IBEC not important then?

So long as you save your ECID with Cydia you're fine to be able to downgrade at a later date ( even after Apple says you can't ).

So all we need is the ECID, not the IBSS or IBEC?? This is so confusing....
