SX-56 AT&T service provider, Unlock question

I have an SX-56 on ATT service that I want to unlock so a friend of mine can use it on T-mobile USA. I upgraded the Windows OS to 2003 summer 2004 when Siemens was offering it on thier website.
I called ATT (now cingular) and they said they will not provide me with the unlock code and to call Siemens for the code. I called tech support at Siemens and they say call carrier (ATT). go figure. They got me with the 2year contract and a sim card id, whats the big deal about giving me the unlock code........
Anyway, found this website and the xdatools. went to the wallaby prompts and when I get to the ROM version the one I have is not listed, so I follow the prompts to the unlisted one and that leads me to the special ROM edition. Okay, that all being said.......I read where it says that the 3.17 ROM is for the PPC2002 version. Does this mean that it will not work with the OS2003 that I have currently installed and if not how do I reload the original PPC2002 that came on the unit new. I am new to all this but am learning so please be merciful if I have mis-stated some things here.
Will I need the ATT sim card in the phone to do all this?
What is the best way to go about unlocking the phone.
the ROM version is: A.30.09 ENG ROM date 01/01/04
the Radio version is: A.33.02
Protocol version: 1.3.3
Any help is much appreciated.
I'm new enough to be dangerous........

No hope for unlock Siemens SX-56 AT&T?
Da** it, you and I are in the same boat with AT&T & Siemens flip-flop game!
My phone is exactly as yours, but I didn't upgrade to 2003. When I do the same way to attempt to get it unlock by XDAtools and pick the T-moblie ROM version like you did, I recieved the message:" the ROM image that you are trying to upgrade is not compatible to your pocket PC. Your device infomation: ROM A.30. Your Upgrade info.: ROM 3.17. Please download the compatible ultility and try agian" And I couldn't find our compatible unlock A.30 version anywhere, either! I also did try the special_rom_1.2 and XDAUnlock, but no darn better news!!!!!!!!! I got the same error message for special_rom_1.2 and got "error getting unlock code" for XDAUnlock.exe.
Pls note: I still have the AT&T SIM card installed in SIM slot.
Any Siemens SX-56 unlock "guru" please help us out.

Is it safe to downgrade the ROM on dash ?

I have a T-Mobile Dash with WM 6
currently i have the ROM version 1.22.531.8 . my question is that is it safe to downgrade it to tmobile's 1.22.531.6 ROM or 1.22.531.4 ?
The reason i need to downgrade is that i want to unlock the phone, however it seems like with the new ROM version, it was not able to unlock it.
TIA!!

SIM unlock remains after a reflash or hard reset.
