Unlock for iPhone 3GS with BaseBand 5.12.01 tested!

We know that a big bunch of iPhone users are looking for a solution to unlock  their 3G / 3GS running the baseband version 5.12.01 (firmware v3.1.3). After some initial hopes, it seems that the dev team is waiting for the iPhone OS 4.0  and 4th Gen iPhone to go official before they launch their unlocking tools. However it seems that one of our readers Shahzad has managed something that works and would be releasing it shortly. According to Shahzad this thing is TESTED and WORKED on his iPhone 3GS, however he hasn’t checked with the iPhone 3G yet.

Here is what his comment reads:

Guys im done with a solution but only for 3GS with base band 5.12.01.
it involves two things,
No.1 you have to buy a 6 in 1 sim, with a sim reader writer, and have to write a bin file on it, that im gona upload on rapidshare.
No.2 im also gona upload a tool for windows plateform, that will jailbreak and unlock ur idevice,
Just tell me what should be the name of this tool, should be different than rain. OK?
sorry for mac users, since i don’t have mac, and sorry for 3G iphone caz i have only 3GS.
