Will unlocked tilt be locked if I upgrade the ROM from HTC AMERICA?

First I would like to apologize if this question has been asked before but I didn't really come across an answer for this . I am a noob at this but I'm trying learn as I go so if some could just give a quick yes or no that would be awesome.

I recently bought an unlocked at&t tilt/kaiser from ebay to use with my t-mobile sim. The phone came with windowss mobile 6.1 htc rom on it but I noticed alot of problems with it such as camera recorder not working and not being able to recieve MMS messages. From this site I learned that HTC America has an offical windows 6.1 rom update for the tilt.

If I upgraded the Rom from tthe site lock the phone back up?

No, it wont. Whatever you do, you'll never relock the phone unless you actually download an application to relock it; basically, it'll stay unlocked forever.
