How to Unlock IPhone 4G?

The ONLY place that can unlock an iphone is the carrier to which it is locked.

Contact them and ask if they offer this.

AT&T, for example, does not unlock iphones at all.

If going by your username the phone is from one of the 2 US carriers then you can't.

There is no Apple product called "iPhone 4G." Check your product name and try again.

Then tell us where you bought it, and the carrier to which it is locked.

You apparently didn't bother to read anything in this thread before posting. The answer is the same. ONLY the carrier it is locked to can authorize an unlock. Contact the carrier it is locked to. Conditions for unlocking vary, but usually require that you establish and maintain service with that carrier for a number of months, are fully paid up, then pay a fee for the unlock. If your phone is locked to AT&T from the U.S. Give up. AT&T will not unlock iPhones for any reason.

Good evening everyone i have same question, i bought iphone 4g 32 gb in ireland from meteor store, and now im leaving this country, what should i have to do but i really need to unlock my iphone, help me people maybe its impossible to unlock it by the factory way?

Why don't you bother to read the posts, tadas?

Contact your carrier.

Purchase your own GSM Unlocked iPhone 4 for $450.00 each, or iPhone 4S for $549.00 each...

You have to purchase a new Micro SIM Card by any phone carriers that use for travel internationally... Enjoy!! 🙂
