It's been several months and the DevTeam has failed to deliver an unlock for both basebands. The crowd has gone tired of MuscleNerd's vague claims and a team by the name of Gevey has resulted to the traditional SIM interposer. SIM interposers have been used several years back to unlock the 3G.

The way they work is described in Singularity's blog,
How did It Work?

SIM card holds many different types of information, but the part most involved with carrier lock is the IMSI number, which is a unique code that corresponds to your account in the mobile carrier's database.

A sample IMSI might look like this

310 150 987654321

The first two segments are known as Mobile Country Code (MCC) and Mobile Network Code (MNC) respectively, and in the example above the IMSI indicate the SIM is from USA (310) AT&T (150).

When the iPhone baseband is loaded into memory, it checks the MCC and MNC against its own network lock state stored in the seczone. If the combination is allowed, the cell radio is activated and vice versa.

The earliest iPhone baseband revisions only check IMSI twice following a restart, therefore it is very easy to send spoof information in order to bypass the check. Nevertheless, the baseband was soon updated to validate SIM more aggressively and the method soon became obsolete.
