Is 3GS (old bootrom) able to unlock (using 6.15.00/ultrasn0w) on iOS5? Or should I downgrade to 4.3.5 (saved SHSH) first?
Got a tip for us?

which are quite out of date and do not mention iOS 5.
" This will work with the iOS 4.2.1 firmware..."
You added the link later, and it does not address my issue. The phone is already on iOS5. I don't need to preserve baseband.
I want to know from someone who has already done this, if I can use the ipad baseband with iOS5.

I don't think you're going to find a lot of people "who have already done this", as combination of iPhone 3GS / old bootrom + iPad baseband 6.15.00 + IOS 5 is a rather unusual one.
Assuming you have a functional JB'ed phone with 6.15.00 - just run ultrasn0w and see what happens. Ultrasn0w supports 6.15.00 baseband, so in theory this should work.
My 3GS is exactly this combination. I downloaded a custom 5.0 ipsw that preerves the baseband after I upgraded to the ipad baseband. Ill post the url link I used to upload the custom rom that preserves baseband when I get home from work.
I think I followed these steps. I have 4.1 shsh blobs saved tho

Currently have a dead iPhone, unless there's something I've done wrong in reviving it. Was fine with 4.1, but lasted about an hour with 5.0.

Try sticking with 4.1 and then download the custom ipsw i downloaded from the link i posted above. I used redsn0w btw
