how can i tell if my iphone 4 is unlocked?
Currently O2 , I am going abroad with it
Is there a any way of telling if it is unlocked already?

Stick a different sim into it?

Or you can look at your installed packages in cydia and see if its installed

if you bought it on contract with o2 its locked. the only way to get it sim free is to get it direct from apple or pay extra from sites like play.com or ebay.
