Yes, the only way to preserve your unlockable baseband on your 3GS is by using a custom IPSW and restore to that.
If you update to official 4.3.2 your baseband will update also.
 
It will if u upgrade it with an official. Use pwnage tool to preserve the bb. I've been updating my 3GS with it and have the same one.
 
Try it with apples server instead to see if it goes thru.

i gave up at about 3am, the first attempt was with apple server then i switched to saurik and refreshed the host file but nothing, then i remembered that i never updated to 4.3.1 so the shsh blob was never recorded for that version so i ended up trying to restore with iOS 4.0 but then i got the error message 1600 (really frustrated i just hit the sack) it is still on 4.0.2 and the modem firmware is still in 05.13.04 at least 😱
