To access my site from my iphone I created some additional files for PGV 4.2.3. Simply copy all files to your root and access the site from your iphone. As a .htaccess file is inside it will switch between the 2 versions (PC/iphone) automatically. If not, just use www.mysite.xx/iphone to force this version.
No original files were changed or overridden.
Everything works fine on my personal site. As I don not use multiple gedcoms, restrictions etc. these things are not tested. I also do not have an strange things in my gedcom that are allowed, but rarely used. So: use it at your own risk!
Any comments are welcome!
