Just got replacment iPhone 3gs it has 3.1 software on. I broke my last one somehow which was blackra1ned with 3.1.2 on it. Now if I jailbreak this one what do I need to do to ensure it stays healthy and doesn't break again. How do I restore it back to normal virginised? Do I have to uninstall blackrain and cydia an just restore back to normal. The thing is is that I tried to restore the broken one but each time it kept coming up not restored error 9. Thanks.....
