Will my phone relock?

Hi,

I bought a Galaxy S4 off ebay over the summer and it was advertised as brand new factory unlocked, I soon found out that the phone was rooted to unlock it, so I used triangle away to remove the flash counter and loaded back on the official samsung rom again as I wanted to receive official updates. However the phone stayed unlocked.

Now my phone keeps bugging me about updating to 4.3 and it keeps trying to download it however i'm afraid it will relock the phone? Anyone have any idea if it will or won't?

Thanks.
