This may sound like an odd question being asked in a forum about unlocking but I am looking for a solution to lock Sony Ericsson phones to any network using MCC-MNC codes. Sorry, my clients require this service. From what I understand there is nothing available for newer model SE phones. I am hoping that you guys might be able to offer a solution. I have a SEtoolbox 3 but it won't work with newer phone security. TIA for any help.
