I've been looking for the most inexpensive set of boxes to unlock all GSM's sold in USA. I have never found a complete solution. This site sounded promising. I went to it and could not find anything about what a "Credit" costs or how to go about being setup. Like I said, I want to be able to unlock all the phones sold in USA. I have alot of Nokia BB5's, Motorolas, Samsungs, LG's, and some Sony Ericssons. I sell refurbished phones for all services. I would also like a CDMA Flasher if there is such a box. The thought of spending weeks online looking for monster mods and FW has kept me from doing this. Let me know. Thanx in advance.
