Hello all. I currently have a jailbroken iphone 3GS with OS version 3.1.2 with AT&T. I have been searching the web with no luck on how to go about updating to 3.1.3 and keeping all my apps. I have made a backup of my phone, and was thinking about clicking update in itunes to 3.1.3 and then running spirit then doing a restore of the backup. Is this the right way i should be doing this? Thanks.
