I jailbroke my iphone last night using purplera1n. I did not backup the iBEC and iBSS before doing so. My question is should I have done this before the jailbreak? Does the Jailbreak alter these files? I was under the impression that they did not, but I could be wrong. Is it still possible or even necessary to grab these off a 3GS that has already had a jailbreak applied? I would like to keep the jailbreak when 3.1 is released. I would hope that I would be ok as long as I backed up the files before I upgraded to the 3.1 release, whenever it comes out. Is this the case? Thanks for the help.
