Isn't 6.1.3 a tethered jailbreak? A bit un-userfriendly to sell. I'd restore it to stock 6.1.3 using Redsnow and your saved SHSH blobs (I am currently trying to find out via the ios 6 thread if that works, so if you are willling to test !).
So selling 6.1.3 On its own not jailbroken and I guess giving the user the option is better huh?
Yes - exactly. Did you already jailbreak it? If you manage to restore back to stock 6.1.3 please report here on how it goes.
Its funny, one of my lines is on 6.1.3 not jail broken and the other is! So I do have to figure out how to restore it...you said redsnow?
Sorry - just noticed you are on a 4S - those instructions are for iPhone 4 only!
Blah this whole time I was saying 6.1.3 but I meant 6.1.2!!
