Guys
I've searched the forums and realise I can buy a SIM unlock code for my Blackstone, however I'm trying to clarify the following.
1. If I install a different ROM do I still need to buy the unlock?
2. If I changed the EMEI (I want the phone to match my in car fixed EMEI - I realise the blackstone has to be switched off when in the car else conflicts) does that mean the phone has to be unlocked again?
3. Once the phone has been unlocked if I change the ROM will it have to be unlocked again?
What prompted the question is reading the Wiki few areas actually simlock the phones....therefore my assumption is a different ROM means it could become unlocked.
Thanks in advance for the help.
Regards
Its an unlocked phone my friend so obviously you pay a higher price for the phone itself able to use with any sim card. Carriers phone that are branded with the carrier logo are usually cheaper with a plan that could cost more then the phone overtime and is locked to the phone carrier which requires a sim unlocking code to use with other sim cards/ other carriers.
The answer to that is you can install any rom on the phone and if it an unlocked htc touch hd which you paid a lot for then it will be unlocked forever
if its locked to a carrier im not sure about that maybe someone can clarify.
any ideas please guys, I get the phone in a couple of hours.

Anyone?
Try to keep this short
1. If I install a different ROM do I still need to buy the unlock?
No Simlock is based on the radio and hardware (short version).
Once unlocked yoiu can up your rom and your radio, it stays unlocked.
2. If I changed the EMEI (I want the phone to match my in car fixed EMEI - I realise the blackstone has to be switched off when in the car else conflicts) does that mean the phone has to be unlocked again?
Got me lost on this one.
Simlock is based on radio and Hardware.
So your IMEI is part of the phone which is either Sim Locked or not.
If you put your sim into what ever is in phone is in your car your number will be the same.
Once you have sim unlocked a device it remains unlocked.
Like I said you lost me.
3. Once the phone has been unlocked if I change the ROM will it have to be unlocked again?
No - Once done it remains unlocked regardless of rom or radio upgrade.
(and if you buy a new Simlocked Blackstrone you cant use your old code as the lock is based on the hardware)

Guys,
I just had a quick question. Does anybody know if I do a factory reset on the phone, will it erase the SIM unlock that I did already from T-Mobile? My phone is extremely sluggish and locking up. However, Iam worried that doing a factory reset will "lock" the SIM again to T-Mobile. Any help is appreciated. Thank you!
You can unlock your phone as many times as needed with that code. The code is locked to your device!
It shouldn't remove the SIM unlock.
I have never tried with the Vibrant, but in me experience with about a dozen other unlocked GSM phones, a factory reset has never re-locked the phone.

Yup, same here.
unknown amount of odin's and roms 2.3 included, never a relock.
Factory reset doesn't even have access to that partition.
You should be able to factory reset with no issues. Once that unlock code is in, that phone should stay unlocked for life.
no, but I wish it does because some people with corrupted imei are having a hard time to fix it.
anyways, you'll be fine.

so does a factory reset wipe out the unlock, and re-lock my vibrant to T-mobile?
If it does then just use the same unlock code because your EMEI doens't change. Correct me if I'm wrong.
No never

Once unlocked always unlocked
I was going to use mobiletechvideos to root the N900T I am planning to buy for use on AT&T. I might even buy a factory unlocked phone.
They have an option called "sim unlock" - They say it is a lower level unlock. If I bought a factory unlocked phone, would a Sim unlock be necessary (if I travel internationally)?
I was selling my phone and wiped the data from it through recovery. I somewhat ****ed up and wiped everything and had to restore from a previous backup. I got it working and sold it, but now I'm being told that the person can't use a TMobile sim card (its a ATT phone that I had unlocked and was using on TMobile). Could my unlocking it have caused the problem? I believe the back up was prior to teh unlock. Furthermore, I had used an unlocking service from ebay. I gave him teh code they gave me and it no longer works. Is it one time use? Thanks for any help.
