So what is the best way to upgrade from 4.2.1 jb untethered, to 4.3.1 jb untethered, without losing any of my data?
Fast replys appreciated
EDIT: Never mind, I found very clear instructions on iClarify. Thank's for the post and the link guys installing and upgrading now
I think the confusion is that the iClarify article doesn't specify (unless I'm just plain missing it) using Redsn0W on an iPhone already jailbroken. The articles are generic and read (again to me) as if the phone is stock. Speaking for myself it concerns me doing this without the steps actually stating this is for stock AND jailbroken iphones specifically.
Personally I'm holding off for a bit to make sure all the apps I use on my 4.2.1 GP jailbroken phone will work with 4.3.1 Redsn0W. Following twitter to keep up with some of them already being confirmed (LockInfo, Mail Enhancer, etc).
