Hey, before my son & I jailbroke with blackra1n back in January, 2010 we followed all the suggestion's. I made backup's of our iPhone's before anything & clicked "make my life easier" to have our SHSH's on file. I since have restored, updated & re-jailbroke with spirit, all is perfect with my iPhone. My son's iPhone I am going to do but I am hesitant because he has been syncing his iPhone with iTunes & his original backup is not there. It is a backup of just last week & the backup is from his iPhone with blackra1n jailbreak. 1) Is it OK for me to update his firmware to 3.1.3. then restore to that backup of his iPhone in a jailbroken state? OR 2) Do I need to look in my PC for his original backup from before jailbreaking with blackra1n & use that backup? Thank's in advance, =)
