I know there are plently of threads on this, but they seem to have conflicting info. I have an iPhone 4 with JB'ed 4.0, and I want to upgrade to a JB'ed 4.1. I don't care about an unlock. Most important thing is I don't want to lose any of my settings, texts, notes, legit apps, etc. I thought the best way to do this was to backup, upgrade to 4.1, restore, and then JB. But I've also read to never restore. So how do I do it? I don't want to lose anything (other than JB apps, which I don't mind re-installing). Thanks!
