Dude Congrats on a new 2.1ViKiD said:Well see rolling back is not possible ...but again the phone wont brick that easily.
Max you can manage is to wipe off the current firmware....even after that you can load a new one! So its recoverable...
Also the toughest part is to install the drivers...
So :
Disconnect phone > Install NPS > Restart > Turn on Debugging mode on the phone > Then connect .
Now remove SIM card and Memory card (remove and SIM locks) ....
Press and hold these simultaneously : Volume Down + camera + Power Button
Asa you reach download mode.... connect it to the PC and let it install all the drivers.
Now restart the system.
Also in order to avoid any issues its best to use Windows XP 32 bit. Or the VM environment in Windows 7 (If on Win 7 64 bit).
Rest can be followed as in Sameer Prabhakars guide.
If anybody here faces any issues. Either you guys can PM or ask for my contact no. ill be more than glad to guide you folks over the phone
Also if you really want ot go back to Andorid 1.5 ...i suggest you use the US firmware ...its wayyy better than the Asian one.
Im currently working on a Hands on and a full Guide on how to Flash/Root/Tweak/etc etc a Spica. but that will require a few more days.
PS: Please register on Samsung-firmwares.com (its free) and you can download the official firmwares asa they are released. I have seen plenty of people flashing again and again due to modded firmwares acquired from various sources.

Do not worry the baseband isn't of much relevance here....(not like the iPhones)
