I don't have any idea about jailbreak or unlock for apple device. Recently i met a guy, he has an used iphone 3gs and it's in a perfect condition (it looks clean, i am not sure about hardware) he agreed to sell me anyhow, he said thats a jailbreak free and i can use any 3G sim card in that with out having any problem. Now i am thinking about what is jail break and what difference does it make compare to a normal one. can i update it with new version? or again i have to unlock that? i am totally confused. please can you explain me in detail.!
