Hi, I have a new 3GS with 3.1.2. It has nevert been JB before but I have contacts, music etc in it. Just now I was trying to JB it and the 1st step I did was to "Shift - Update" to 3.1.2 firmware to make it a "virgin device", but I got an error "device not eligible to restore the build requested". Anything went wrong? Also, since my 3GS has never been JB before, can I just use blackra1n to JB it without "virginizing it"? Your advice is much appreciated.
