These hacks all require a SIM card passthrough to be used. They typically work by spoofing the MCC/MNC.

Old SIM Exploit

This relies on the fact that the IMSI is read twice, once to validate the IMSI and once to connect to the network. So the SIM card spoofs the first IMSI read to trick the device into thinking it is operating on the AT&T network, or whatever network the device is locked to. The second time it allows the IMSI to be read properly from the sim card. That is the IMSI sent to the network.

A slight variant of this exploit uses a silvercard to program the IMSI and ICCID differently. This variant requires your Ki to be known, which can only be extracted from COMPEMU v1 sim cards.

SIM Hacks for iPhone 3G

iPhonix / Juma

MacBug.de reports only 2G mode works with this.

TurboSim

Indications are that no stable TurboSIM exploit is available at this time. For some providers in Germany there appears to be some success, see TurboSIM Unlock.

StealthSim

Initial reports on Hackint0sh Forums indicate full 2G and 3G function. However these are new posters with small post counts. More information on this is strongly requested.

Yessim / Furiousim

Conflicting reports on whether this works. Samples have been provided to various users on Hackint0sh Forums. Initial challenges faced because of a RJ45 type connector that is needed to set "Boost Mode". It is recommended that if ordering, the USB "YesUP" or "FuriousUP" cable is used.

iPhone 3G Warning

The iPhone 3G SIM tray is very very thin. If using SIM hacks (dual sim, etc.) a long thin tape should be attached in a way that you can easily extract the sim tray without relying on the normal tiny SIM ejector button. You have been warned.

Should you not apply tape beforehand, you can still eject the simtray with an L-shaped pin and a quick but forceful yank. It sounds scary but it's just plastic, after all.
