If your able to put a virgin/vodafone/o2 sim card into an iphone and use them other than not getting a good signal on 2 of them does this mean the phone is already unlocked.

If you get a signal its unlocked.If its a locked iphone it throws up an error message and all you get is the itunes logo.

I've been able to chat on another network other than sometimes suffering dropped calls.


I don't seem to get any error msgs and i always get the apps screen etc appear.
