Cingular 8125 on T-Mobile

When i got the Cingular 8125, and before I did the ROM Upgrade to 2.17.7.2 WWE, I did the recommended CID Superunlock. As far as I could tell everything went great. Unlocking this phone, to me at least, meant that I would be able to use it on other non-Cingular GSM networks. A little bit ago a friend who is on t-Mobile needed to use my phone to make a phone call. He put his sim card in my phone and gave it a shot. When the phone started i was getting an error message about a network being locked. I do not remember the exzct wording.
Any ideas if this implies that the unlocking procedure i did di not work succesfully? or am I missunderstanding what the unlock procedure is meant to do? Is there another unlock procedure to make this phone usable with other providers other then Cingular?
Thank you

The CID unlock allows the installation of firmware with a different "brand" than your hardware was sold as. It has nothing to do with the GSM SIM. Use the latest version of lokiwiz to SIM-unlock your phone. Do a search for lokiwiz and read up on it.

use Lokwiz to SIM Unlock it. CID unlock allows you to flash other Roms.

Yupe.... I did what 'Kyphur' mentioned to used my Tmobile card in my Cingular 8125. I bought Cingular because I like the 'Square' compare to the round design that vario have.

2.17 rom for 8125

basically im new to updating roms, and i wanted to know what do to. is this just a direct update...i understand i need to CID unlock with lokiwiz2, but after that im completely lost. any info thanks
is it worth going from the Cingular 2.25 rom to the 2.17 one?

You wont' need to do any unlocking to upgrade from the 2.17 Cingular ROM to the 2.25 Cingular ROM. The CID unlock would only be needed if you want to run a homebrew/custom ROM or a ROM from a different carrier. CID = Carrier Identification (lock). Essentially it's just like upgrading the firmware on a cell phone. IMHO and in my personal experience the 2.25 ROM is much more stable than the 2.17 version. I'm not sure if 2.17 has A2DP (push email) built in or if you need the hack, but I'm sure that 2.25 has it built in. If you like what you've got, there's not a great reason to upgrade as you will have to reinstall all of your programs.

unlock-upgrade

I have sim unlocked my cingular 8125 with the old ROM 1.8 everything worked perfect.
My question is if I want to upgrade the ROM to the 2.25 my phone will be locked again?
I m afraid about that and I can not unlock it again.
Thanks.

Upgrade to new rom

I have just bought a 8125 running 1.8.11.1 rom, 11/24/05. This phone is unlocked and I am using my old AT&T sim. If I upgrade to the new 2.25 rom will my phone still work with the AT&T blue sim.
Thanks so much!!!!

followup
Just checked and it is not cid unlocked. How can this be working with my blue sim?
Will the new cingular 2.25 update diasable my phone.
Thanks so much for your input!!!

Cid unlocking unlocks your phone for using custom kitchens. Sim unlocking unlocks your phone to use other providers sim cards. It is best to unlock both. Use lokiwiz. There is a sticky somewhere in the wizard section of xda that will tell you how to do it. Read everything carefully. Any modifications you do, you do at your own risk. Read the wiki, the stickies, etc before customizing. By reading it, you understand the how's and why's.

If my phone is simm unlocked now and I upgrade rom to 2.25 off HTC cingular sight will it still work with my AT&T blue simm?
Thanks!

As I said before...once cid/sim unlocked, always cid/sim unlocked...flashing different roms will not relock the device...BUT it needs to be both cid/sim unlocked if you are flashing from a kitchen. And yes, if it is sim unlocked, ANY sim will work in the device.

As long as you have a SIM it will work...it does not matter if you have blue, red or yellow...
CID unlock will help to install different OS...READ (I mean READ!!!) the wiki and stickies...

thanks so much for your replies. I did upgrade to the htc 2.25 rom and really dont see much difference and yes the sim still works.
Thanks again
