Hi I have an iPhone 4S currently running a jailbroken version of 5.01 I would really like to upgrade and jailbreak to 6.1.2
From what I gathered, I have to do an iTunes backup, restore that backup. And then update through iTunes. Is that correct?? Also, once I upgrade, will I lose my SMS messages, or are those saved in the restore process? If they aren't, is there a way I can save them??
My last question is concerning downgrading. I have blobs saved back to 5.01. Will I be able to go back to any of those versions? I keep reading different things about that.
Thanks so much for your time! Any help would be greatly appreciated! :)
You need to restore to kill the jailbreak.
Back up in iTunes- restore to 6.1.2- jailbreak- then restore from your iTunes back up (best to jailbreak without a lot of data)
Your contacts, pics, etc, will be saved in the itunes backup. Make sure your media (apps, music, etc) has been transferred to your itunes library otherwise you'll have to redownload them.
Unfortunately for A5+ devices like a 4S once on 6.x always on 6.x. The 5.x SHSH become useless.
