Cingular Nokia 3595

OK everybody, got a problem....

Company switch to cingular, I buy a nice brand new Nokia 3595. Think ok great, now I can play midis and download from WAP sites,and other GRPS functions.

Here's the problem, cingluar has locked out GPRS functionality, so I can not send and recieve MMS's or visit WAP sites. My wife has AT&T service with a Siemens S46, and GPRS service. If I can unlock my 3595 I should be able to put her sim in my phone and download midis and what not, from WAP sites.

Here is my info:
Serial: 010185004389356
Oper: Cingular USA (California)

I have tried on one code graciously provided by MrWolfman.
#pw+013503244157400+1#
All I get is Code Error...

Anyone else out there have anything for me?

Thanks much!
