Everything worked....except one thing :-/
As you are well aware of by now, great guide and thank you very much. I purchased my iPhone off ebay and it was already jailbroken, unlocked, activated, etc... however when I popped my T-mobile SIM card in it it displays "Locked SIM". I restored it via iTunes to Firmware Version 1.1.4 (4A102). I followed your guide step by step to the end. Here is the problem, the settings for BootNeuter were already exactly the same as what you say to change it to. So I press Flash and it says there is no need to flash because everything is the same. So instead I downgraded to 3.9. After this the "Locked SIM" in the upper left corner of the screen goes away and it displays the bar icon showing barely or no reception. It remains this way for 15 seconds or so and then reverts back to the "Locked SIM" display. After this I went back to BootNeuter and upgraded back to 4.6. However it changed nothing it still did the exact same thing. Any ideas why everything is done but the SIM card remains locked? I have T-Mobile just like you so it should work right?!?:confused:! If you could help me out I would appreciate it very very much. Thank you.
