Deep breath.... I did my husband's phone to 1.1.3 via the large thread here which upgrades the baseband for AT&T, etc. For my pristine 1.1.2 jailbroke phone - I'm tempted to try via the Official jailbreak in installer. I've moved everything to the other partition via Boss. I've upgraded to the latest Installer. Does anyone have any other words of wisdom or prep suggestions before I start the horrifying process?
