Is my HTC 3600 Locked or Unlocked? - Upgrading, Modifying and Unlocking

Hi, i bought a few months ago from one guy one used HTC 3600 that i'm using with no problems.
Now i want to upgrade the current WM5 to WM6 using one of the roms that i found on this website.
From what i understood .. and i'm currently noob at this i need First to Unlock the HTC.. then i need to flash it with the new ROM.
Question is... how can i know if the mobile is already unlocked?
I believe that he currently accepts any SIM card and it's not SIM-LOCKED but i'm not sure if this is related to the ROM lock or something.
Help me out if you can.
And if it's unlocked or locked can i flash it anyway or it's mandatory that i need to unlock it to be able to flash it?

Greetings
I purchased this from ebay http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=320119641811 a couple of months back it works with any network. Does this mean its cid unlocked for flashing purpose or do i need to unlock the rom to enable a flash upgrade
You need to follow the CID unlocking proceedure on the Windows Mobile 6 part of the forum every time before you flash.

An unlocked phone may be locked again?

I got an unlocked at&t fuze(touch pro) few days ago. I don't know how it was unlocked. I wonder if it may be locked sim again after upgrading a rom or radio?
Nope man. I think it has to do with the radio or something like that, not the ROM. But to be safe lets hear what more knowledgeable members have to say.
new roms or even radio roms don't relock phones
Fuse locked or unlocked?
How do I confirm that the phone I bought that was suposed to be unlocked actually is?
Thanks
You can install all roms that u want... and if you want to relock your phone, you have to do the work with a separate tool

How do I unlock the phone

Hello
I recently came into possession of a sony xperia lt15i which is currently on Virgin (UK) and I would like to unlock the device. Its currently charging so I cant advise the OS.
Can anyone offer some help please
the software version is 2.3.4
You can unlock the Bootloader by one of three ways and Sim unlock by one, which is to pay for it.
Hi mate,
Mine was locked to Virgin UK, I unlocked via the test point method. Below is a quick guide I made in a previous post:
http://forum.xda-developers.com/showpost.php?p=30011599&postcount=4
This method does unlock the Boot loader though, not sure if you want to do that yet.....
Hope you find it helpful
BTW: it doesn't matter which firmware your running.

[Q] Carrier Unlock Question

Hello. recently I read on a section of the HTC One X forum that if you want to unlock the carrier of a HOX and you have a custom ROM flashed and bootloader unlocked you need to lock back the bootloader and flash a stock ROM. Is it true, or can unlock it with the custom rom flashed?
You can`t disable the carrier lock without s-off.
Thanks for the answer. So there is no way someone could unlock the carrier if i have S-on?
No, sorry....
There is no way without S-OFF.:angel:
You can unlock your carrier to allow different network Sims, just google "HTC one x carrier unlock".
It's not possible to change your cid without s-off

Here comes the problem.. I know that cellunlocker.net is trusted when comes to unlock codes and i got my code yesterday. I was on Custom ROm with bootloader unlocked. When i enter the code it says it's incorect so that's why i need to know if i need to relock the bootloader and go on stock rom?
I had the same situation.HTC locked device with the code you can find on websites but then your carrier changed unlock codes,and the one you bought from site is incorrect.
I asked my carrier to tell\sell me the code but they dont want to untill the warranty is over.You can ask your carrier also,it doesnt cost you anything
My local phone repair service tell me that only solution for me is to take apart phone and read codes directly from motherboard but then i will lose warranty,which is ok for me,i already unlocked bootloader and root my hox
Just relocked and flashed stock rom. I will contact the carrier and try to get the code. Thanks for the help.

Unlocking T-Mobile M9 phone?

I have a question and could find an answer, well maybe a few... First if you have an unlocked version of the m9 directly brought from HTC all updates come from them not any carriers? With that being said if you by a T-Mobile version and get an unlock code from them will updates still come from them or HTC?

HTC updates the phones sold through HTC. Any phone with carrier branding has HTC submitting their software to the carrier, and then it's released after carrier approval. It makes no difference if the phone is locked, unlocked, used on a different network, etc.
The only way you can go about getting updates directly from HTC in the past is through S-Off and a CID change, effectively changing your device ID, but A: I'm not sure if this is still the case and B: If you're asking the question that you asked, this is going to be a bit too complicated for me to explain at the moment. So the simple answer is No.

If you unlock the phone you will have to manually update the phone. If you stay stock you will get updates from T-Mobile, although they will lag the official (and XDA unofficial) releases by a substantial time.
Most folks unlock because they want to flash a custom ROM anyway, and will get updates on that ROM, rather than HTC or T-Mobile.

hmmmmm actually depends on which UNLOCK. If he meant unlocking it to make it carrier free but leaving everything stock then it'll update automatically. If he unlocks the bootloader but still remains stock without changing anything then it'll be auto still. I believe the only time you need to manually update is when you alter the recovery partition of the phone (installing custom recovery CWM/TWRP/etc) which means you'll probably run a custom rom, which also prevents automatic updates.

I'm assuming he meant unlock the bootloader, not the carrier. But I personally would not go to the trouble of unlocking the bootloader unless I was going to go custom ROM.

yeah I got that, but he said unlock code and from T-mobile so I deduced it to carrier unlocking lol.
Well I actually already unlocked the boot loader and using custom ROMs so not that be of a deal more so for my understanding. So if everything was stock and just got an unlock code from T-Mobile to unlock the device and say used the phone on AT&T or Verizon where would the updates come from ? The carrier you are on at the time or HTC?
By the way that's for the help and responses guys!

You are not going to get updates for a T-Mobile phone while on an AT&T network, even if you stayed stock. I don't think the download would work, and even if it did the ROM would not work with your variant. I think they will detect that your phone is not AT&T and not even offer the update.
It sounds like you have installed a custom ROM. In that case you won't get OTA at all, from anywhere; you simply update the ROM when the developer releases a new version.
