UPDATE 1:(if your iphone is manufactured after 28 week 2011 you shouldnt use the ipad baseband as it will brick your phone.to check your 3gs manufacture date, go to this site( http://www.chipmunk.nl/klanten... ) and enter your iPhone’s serial number in the given box. To find serial number, go to Settings >> General >> About >> Serial Number.)

dont use this on iphone 4 if your baseband is not already supported by ultrasnow and dont install the ipad baseband on it. just follow the rest of steps.
