I want to buy the new iPhone 4 but I got a question. I travel a lot, I live in the US and twice a year I go to Colombia which is in South America. I know that I can make calls but that charges a lot so I wanted to unlock it first. Is unlocking the same thing as jailbreaking, is it illegal and would it void my warranty? I would want to be able to put a another SIM from another country and make it work.please be specific in you answer. Please help, thank you!

The iPhone 4 has been unlocked and Jailbroken using one of three exploits found by the Dev Team, they are currently testing the other two, and by the time you get yours, it should have an unlock ready. Remember to save save your SHSH's though.

P.S. if i restore is there any way of telling i jail-broke? and lets say a new apple firmware comes out will i be able to download it?

No, there is no way to tell that you Jailbroke if you RESTORE and SETUP AS NEW. Also, you can read up on SHSH's at the following link.

If you're on 3.1.3, Jailbreak using an Jailbreak tool called Spirit, available for download at


I hosted it on my site. Once you're done with that, download ultraSn0w from the Cydia search, make sure the version of ultraSn0w is 0.93.

Then insert a foreign SIM card, and you're good to go.

Click the restore button in iTunes, then click set up as new. Simple as that. Apple can't detect a thing, just the date and time that you last restored.

I have read somewhere that you can just put another sim in BUT after 2 months (not sure) AT&T will block your phone or something if you don't use it regularry with AT&T's network

That is 100% completely false. They can be sued for that. They cannot ban you from their network unless you are affecting their network, and harming other people's service.

they don't ban you, i think you can't call anymore unless they unblock it.

but I'm not sure if the source i read it at is reliable

If you buy the iPhone 4 you will half to wait for someone like the Dev Team to come out with a jailbreak for it and then an unlock for it. You will have to jailbreak it then unlock it. Jailbreaking and unlocking is not illegal but it does void your warranty, but if you ever have to bring it in to apple for some reason all you need to do is restore and apple would never be able to tell that you jailbroke it, just remember to put your att sim back in the phone.
