Dear Lazy,

I think the title needs a little modification, because i was browsing dev-team websites, and i'm afraid there is no tools for 3GS for now on OS4 ... no jailbreak, no unlock.  


read on Dev Team Blog

So ... If u can't jailbreak it, how can u unlock it ??

Please correct me if i'm wrong, ( i wish i'm wrong, so i can do my phone   )

thank you ...
