Or Google for a free converter into 3ds format as this is the most widely used format for 3D models.
Your model may just have solid colors but if it also has textures to display, then zip it together with the texture files (jpg's png's and so on), change from .zip to .3dz and you've got a self contained 3dz model file, ready for viewing in i3dViewer. AllMasterSoftware products also directly create .3dz files. Easily copy files directly to your iPhone/iPad using Windows Explorer if in wifi range. Or send models as email attachments or use FTP.
