So I'm going to upgrade to 5.1 from JB 5.0.1 and I need some help here. I'll be looking to setup my 4S as a new iPhone and restoring all of its data so here's my question. Should I update to 5.1 and then follow the steps here (http://support.apple.com/kb/HT4137) to Erase and Setup my 4S as a new iPhone? Or Should I Ease, Setup as new and then update to 5.1? Thanks guys!
