I currently have 3.0 installed and want to upgrade, but I was wondering. If I use the custom IPSW method, can I just use shift+upgrade to upgrade to 3.1.2 or should I clean install? If the latter is the case: 1. Can I just restore my old info 2. what is the best method to restore my custom apps+ repos, I used appbackup (I think thats the name) and it was rubbish as it didnt restore everything. This is my first upgrade to a minor revision so excuse how noobish this sounds.
