You may come across many different articles and videos about how to unlock you iPhone, on the web. But from my experience many of these so called iPhone unlock methods are outdated, do not apply to your model, or do not work. I had a iPhone 3G that was locked to the AT&T network. I wanted to take this iPhone with me when travelling and use another sim card, but found it impossible to get my iPhone unlocked.

I searched the internet looking for free solutions to unlock my iPhone, but they did not work. Eventually visited a iPhone unlocking company. Most of the companies listed are well known and reliable companies who can guarantee you that they will unlock your iPhone for you within minutes. You simply give details of your model number, IMEI etc and they generate a code. If that code doesnt work they generate another. If they cant unlock you iPhone they dont charge you. Give them a try, I did and was happy with the service.

Dont waste time trying to find a free solution to unlock your iPhone. If you have a normal cell phone fine, you can get the unlock code online for free some of the time. With the iPhone you need to visit a reputable unlocking provider. I heard of free unlocks that totally ruin the iPhone preventing it from re-booting. I wouldnt take the chance. Try the recommended iPhone unlocking companies, they are experienced at unlocking all models of iPhones.
