NO GSM? Phone wont work on WM2005!! what's wrong?

[damnation]

hi i used Buzz's WM2005 rom and didnt change the operator value cause i dont know what it does and i don't know what to set it to
im in australia and with telstra communicate prepaid, but i cant seem to connect after upgrading, what should i do, is it indeed the operator value i need to change, the only error i get once it's booted is that it wont connect to my network, and when it's _booting up_ it says NO GSM next to rom ver.
what do i do?
sorry guys i couldnt find much info to directly help me, any help would be appreciated

Also, i have a huge other prob, i put a lock on my phole and then i switched it to landscape mode
then it turned off cos i went to the toilet, i came back, turned it on and it had the promt to enter the ping/ password (numerical in this case) and it wont let me put in/ it wont let me input numbers, however they are there, could this be cause due to landscape switching??
i dunno im freakin out, cos i re-upgraded and the pin/ pass is still there :S
HELP~!!!
