what is network code for USA, Cingular (for use with imei calculator)?

[dluik]

Hi have been unable to unlock USA Cingular handsets using the unlock code calculator.

The site i normally use :
http://www.gsmworld.com/roaming/gsminfo/index.shtml

shows the following network information for Cingular:

Network Code 310 150,170,410

I assume the above to means
310-15
310-17
310-41

so far I have only tried 310-15. Anyone with any info on this please help!

Kind regards

Dan
