I have iBEC, IBSS, and ECID. Can I use them?
I read from many posts about "on file" process on Cydia's server.
Can I do any different process since I have all the required files and security information of my hardware?
My iPhone is locked 3GS with 3.0 OOTB but I used ultra and red to unlock and jailbreak. Now searching through some forums for 3.1 update and got a little bit confused. Pwnagetool is for Mac to create the custom FW without updating the baseband; does this tool requires iBEC, iBSS, or ECID in order to create the custom firmware?
Still not quite understand "on file" thing on Cydia's server. If those files are the same as my iBEC, iBSS, or ECID can I utilize my files and some tool to jb/unlock (OK if I stay on the old baseband I need no unlock...)
Please educate me.
