If you're one of the million people that have purchased an iPhone, you probably signed up with Apple's exclusive carrier in the U.S., AT&T, when you activated your phone. That means your iPhone identifies itself to AT&T's network using an AT&T SIM card, a smart card that's located in a small tray between your iPhone's sleep/wake button and its recessed headphone jack.

But what if you want to use T-Mobile or another network or maybe you're planning a trip to Europe and rather than paying AT&T to use the networks of its European partners, you want to take advantage of the favorable rates and local phone numbers offered by replacing your AT&T SIM card with a pre-paid European card?

In the past months several groups have announced that they've found a way to "unlock" the iPhone, allowing it to use a SIM card from any provider. (Keep in mind that this is only half the story: the iPhone uses the GSM radio band for its communications, meaning that it'll only work with providers that use the GSM network. In the U.S., that means T-Mobile and AT&T.)

In August, a group of hackers demonstrated a method for unlocking SIM cards and sold its software to resellers, who in turn began selling it to the public for as much as $100 last week.

But another group has come up with a Better, Safer, and more Affordable way that lets you unlock your iPhone in about 15 minutes for only $9.95. It does work, because I've used this technique to unlock my own iphone. This program is available at Berry Smartphones and another great thing is it allows you to get tons of free apps.
