iPhone DevTeam: stay away from any updates to 3.1
http://img.qj.net/uploads/articles_m...nth.png?911019The iPhone Dev Team is back with another warning concerning updates from 3.1: stay away from any updates to 3.1or else you will not be able to use Ultrasn0w, so please re-read and double check the following warning below (emphasis theirs):
You may have read or heard about techniques to capture files during the iTunes restore process. These will be required to jailbreak your phone in the near future, most of the methods involve icky USB snoops. Well, there is an even better and more reliable method to get your hands on those lovely files.
During the restore process iTunes nicely keeps these oh-so-top-secret-files in a lovely accessible place for us to copy out and backup, that place? /tmp on Mac OS X or TEMP on Windows. Thanks Apple handy!
The downside to this approach is that you actually need to go through the restore process to get these signed files, which has risks if you are anywhere near 3.1 or 3.1 beta :-)
If you are ready to proceed and you know the risks we ll get down to the nitty-gritty:
So during a usual recovery with iTunes, your signed iBEC is written to /tmp and during a DFU mode restore the signed iBSS is written there also. To be sure, restore in both modes one after another to be able to grab them both. You ll need to keep an eye on the temp directory and copy it before it is deleted again by iTunes. I m sure some nice folks will create a tutorial about this, we ll link to the first person who makes a good one.
Should you choose to accept this mission, act fast, this needs to be done quickly! But again, always, always double check here to see if 3.1 has been released, if is has, then don t do this.
So there you have it. If UltraSn0w is particularly significant to you, then be very careful with this method. Also, if you have downloaded the 3.1 beta, then do not even attempt this.
