If you set up your new iPhone using the backup of your 3gs, the camera roll will transfer. Sync old phone, then sync new phone, secondary-click on the phone name in the left sidebar of iTunes, then select Restore from Backup and select the backup of your 3gs.
Alternatively, sync the photos from your 3gs to iPhoto, then add them to an album and sync that album to the new phone.

My knee-jerk answer is you don't transfer your camera roll to your new phone, you have the pictures safely stored (and backed up) on your computer. If you have a camera, and buy a new one, do you seek ways of transferring pictures from the old to the new?
