Right, ive realized renaming the file as .ftf is not the thing to do. i unzipped the zip, which made a folder full of .sin files, used flashtool/advanced/bundle creation to create a .ftf from the files in the folder, this seemed to work. however, i still cant flash the .ftf to the phone! it wont even let me flash the CE1 Generic .73 .ftf that is already on the phone!!
