Attaching is a pain!
Trying to attach an image to send as a fax is a pain! To get IFax to recognize uploading a photo from library takes trickery, then attaching the file doesnt load and save, then it freezes the application. Dont use IFax if you intend to try and send faxed items that have not previously been scanned physically!
