Simox: not sure if this has been mentioned here before or not (94 pages in this thread -- DAMN!), but I found a good way to check if the simlock patch works. Key in the sequence > * < < * < on your SE phone to enter the Service Info submenu. Click on SIM Lock and if the patch works, you should see Network has an "unlocked" icon and the number 5. If patch didn't work, it will have a "locked" icon and the number 10. Hope this helps others! (maybe you could add it to the 1st post too? Thanks for the update on the rest file, your tutorial is looking great)
