We have just got our hands on an old Ipad 1 which we bought from John at John and Ginger. So we can now fully test new site builds on Safari for Ipad and Safari for Iphone. The safari for Ipad give pretty much an exact copy of a site as Firefox and Google chrome, but do not expect your site to work the same on an iphone.
We have even cleaned it up and bought a new leather case of Amazon for it. Who needs an Ipad2 when the first one does the job anyway.
