Apple iPhone 3G: Sim(ple) Unlock

“Choose Your Carrier…Again”

FuriouSim claims to have a working sim-based unlock for the iPhone.

A large slew of sim-altering devices flooded the market soon after the original iPhone was released. It was only a matter of time before they resurfaced to exploit the carrier locked iPhone 3G.

FuriouSim works by “tricking” your iPhone into believing you are using an AT&T sim card. This “unlocks” the iPhone, allowing you to make calls on your own network.*

Sim-unlocks have notoriously claimed to be impervious to iPhone firmware updates, yet, a relatively unheard of FuriouSim becomes first on the scene with a (claimed) “working” carrier unlock for the iPhone 3G.

Wikipedia Exerpt on Sim Unlocks:
The Turbo SIM (also known as TurboSIM) is considered the forerunner of a large family of “Dual SIM” devices (HyperCard, HyperSIM, China3GPP, StealthSim, MagicSIMetc.) that piggyback on a telephone SIM card to alter its normal operation.

More specifically, the Turbo SIM can be used to spoof the IMSI number and authentication key (Ki) supplied by the SIM card to the network, allowing network-locked phones (such as the Apple iPhone[2][3], and more recently NTT DoCoMo and SoftBank phones) to be used on mobile networks for which they were not originally designed or permitted.
