Important question on software locking and unlocking, please help!! :(

I recently bought a blackberry 7290 on ebay, which was originally locked on cingular.
THAT'S THE PROBLEM
I want to synchronize my blackberry on my computer, but to do this, I need to upgrade the software of my handheld to a newer version (I have v3.8 now)
I currently use my cell phone on the FIDO network, because it is unlocked.
If I upgrade my blackberry using the CINGULAR update, will my phone be relocked?
Else, which upgrade should I use?
You can use any version of Desktop Manager with the 7290. The latest version of the Handheld OS is v4.1 for the 7290. The latest version of DM is 4.2, which has additional features (like the Media Manager) that can not be used on the 7290. But you can install and use 4.2 DM.
