[Q] SIM Blocked

When trying to change my SIM Card pin my phone just locked up and went to a screen that says:
Emergency Calls Only
Please see the User Guide or contact Customer Care.
It's on T Mobile UK and has been fully rooted, and is running the latest CM7 build.
When i go to enter the PUK code, it allows that but does not come up with an option to click next, and when i press dial it just tells me that it's not an emergency number.
Any ideas?
I have worked it out. If anyone else has this problem then this is how i solved it:
Tap Emergency call and enter the following sequence using the keypad: * * 0 5 * [PUK] * [new PIN] * [new PIN] #
Click to expand...
Click to collapse

[Q] Choose baseband (eg WCDMA 850)

I'm coming from the Samsung Captivate, and on those ROMs I could choose which baseband I wanted to use based on performance. I used to access that by entering #*#*2263*#*#
Is there any way to do something similar on the GS3?
