Default [Q] Need a modem

Thanks to the beautiful works of s0be, to whom I owe a working phone, I'm back up and running. However, getting his ROM working on my device was only half the battle. Unfortunately I still don't have a baseband to use. EDIT: I just realised my brother has the same phone as me. Could one of you guys tell me how to extract the modem from his phone? Thanks in advance. EDIT 2: I'm freaking slow today... Just looked up "How to back up modem" and got like 20 different hits on Google.
