dear sir,

I want to unlock my iphone 3gs 3.1.3 firmware baseband 05.12.01, these companies offering unlock for all models of iphone 2g, 3g, 3gs for all firmwares, but when I bought their products, they give a note stated that for iphone 3gs 3.1.3 firmware baseband 05.12.01 is not yet available at the moment, and they will just give a free update.

They are offering also a money back guarrantee to convince a customer. till now no one is replying to the mail that I sent them regarding my complaint. beware!!!
