I have an App developer that is requesting an .AI file for developing an App that can be utilized on all the following Apple hardware (iPhone 4, iPhone 5, iPod touch, iPad, iPad mini). He is insisting on it, because of the vector file. I have a design file that was completed in a layerd PSD. I want to know what, if any, quality is lost from converting from PSD to .AI vector file? Would it be better to have the Designers strach over from Scratch? Please Advise!
Thanks for your help
