So I bought my 2g iPhone activated, and when I tried to unlock it, it took me forever to get. Using the old sim card, I jailbroke it and installed OpenSSH so I could replace the springboard (I think?) files. It has worked fine ever since, but I am on 2.2.1 and desperately want 3.0 at least. Does the fact that I had to change all that stuff make a difference in my updating and jailbreaking? Or will it re-lock and f*** up?
