Hi i think that you should download a previous sdk version (so an xcode too) ..so you should search for a compatible sdk version with iphone2 .This link may help you http://iphonesdkdev.blogspot.com/2010/04/old-versions-of-iphone-sdk.html (install this sdk in a folder different from the developer one to mantain the current one)
