Samsung I7500 :: Flashed I7500XEJC6 - Won't Read SIM Card

I've currently got a Bell Samsung I7500, I flashed I7500XEJC6 onto it with Odin (using this site http://mauweb.net/3.0/en/technology/17-android/99-icon-androidsamsung-galaxy-i7500-upgrade-1634.html) and was able to get it from being in some foreign language into english again.

But now it loads up with SIM Network Unlock PIN, when I have a Bell Sim card in. I can either enter the pin, or dismiss the message.

If I dismiss it won't read the SIM card and therefore has no signal. I was able to get the WIFI to work, and got into the marketplace. I had already downloaded Drakaz's updating software, but there was problems with that before I flashed the Baseband. I took a picture of the problem with the Galoxo system running (I went back to it to see if that would help) for reference.

Now I can't seem to find any way to get around this. I asked Bell if they could give me a code to lock it to to their Network. When I called them they tried numerous codes but none worked. They said after it loaded without the SIM card in without that message, that I needed a new SIM card. A new SIM card however didn't work. Same message.

I tried getting a company online to get me an unlock code, but their answer was that "There are so many mobile out there sometimes the firmware on certain versions mean I can't generate the code. Your only option may be your network operator or a local shop who can unlock via a cable."
