Apple sent me a refurb 3GS this past Tuesday, I activated the phone through iTunes to firmware 4.0...it has the old bootrom as the buildweek number is 22. The description for sn0wbreeze says your 3gs has to be jailbroken ALREADY for this to install properly. Since my phone isn't jailbroken right now...what are my options? Do I have to wait for a jailbreak that will work for the phones with the new bootrom? How can I jailbreak this thing? 3GS on 4.0 using Windows. Thanks in advance everyone!
