There's two different kinds of stock roms: dumped and shipped.

If you use a dumped stock rom ...your carrier will know you've unlocked it even though it's a stock rom and thus void your warranty. Dumped stock roms do not relock your phone.

All stock roms on htc's website are shipped and relock your phone.
