Im new to this. i have a tmobile dash and i currently use tmobile as my carrier. so would i have to unlock the sim to update the rom? from my understanding as long as the CID is unlock i should be fine right?
No it is not necessary

Can some one explain the difference between SIM and CID unlock.
I have updated my ROM to latest version from T-Mobile and I get my SIM unlock code from T-Mobile to. I would like to know if my MDA is CID unlock to.
I have an HTC Fuze (P4600), and I unlocked it.
However, its running ROM version 1.x, and I want to upgrade it via the official upgrade through the HTC website.
What I'm wondering is, if I upgrade, will I lose my SIM unlock, because I do not have the code.
Thanks.
You will not lose SIM unlock with ROM update.
I hope so.
Updating now, will post status of SIM unlock after its done.
I have SIM unlocked my HTC Desire long time ago
where the original lock was for Telus.
Now my volume button does not work and I want to send it back to Telus/HTC
for fix and just to be 100% with the procedure I want to re-lock the SIM
back to telus
I have the unlock code which I used the first time and I guess I can lock the SIM
using the same code
Does anyone know the procedure for re-locking the SIM to a specific network
and do I need a telus sim card for that?
I think you have to unroot it with a ruu

Rooting and sim unlocking are different procedures. I doubt that flashing stock will relock your phone.
Anyways unlocking your phone with an unlock code doesn't tinker with your software so it shouldn't affect warranty. But I guess that is up to the provider to decide.
Right now I have CM rom
I will flash the original Telus Desire ROM and I want to re-lock it
As paul mentioned by flashing the original rom it does not mean the phone
will be sim lock again to telus
There are some codes with *# but I can not remember the procedure
i think there was a simlock in hboot or fastboot i think
currently on ariel rom, with an unlocked att gs3. would like to restore device to stock and upgrade to JB to sell on ebay. will switching roms or upgrading android version cause me to lose carrier unlock?
Anyone?
Which method did you use to unlock the device? (For example, standard SIM unlock, dialer code/"ServiceMenu" method, etc)?
The phone was used on t mobile briefly but I couldn't stand edge speeds. I called att and they gave me a code to enter after inserting the t mobile sim card. When you turn the device on with another network sim card it automatically prompts you to "enter unlock code"
No. Switching roms or upgrading android version will NOT cause you to lose carrier unlock.

Thank you very much
If my device was originally AT&T branded but then bootloader unlocked, then S-off, and super-CID....... ... and now has latest developer firmware flashed with Custom 5.01 ROM , like LeeDroid's latest Sense 7 -- will that phone be "carrier unlocked" if I were to try to use another SIM like from T-Mobile??
I don't have another carrier SIM to test it -- planning to sell

No. SIM locking is separate from CID/MID locking. Unfortunately, since you have flashed the most recent firmware, the one hack that used to work is probably unsafe to attempt at this point. Instead, you will need to get an unlock code from AT&T or buy one from a service. (or inform the buyer that it is still SIM locked to AT&T, but that's going to cut the value a lot)
