I have a template of teline III also configured to display on Iphone, it initially did but is not longer giving me the Iphone display and is now displaying the standard webpage on Iphone. Cleared the cashe on the iphone and reinstalled Iphone.php in /templates/ja_teline_iii/layouts.
This did not fix. Just reinstalled /templates/ja_teline_iii/layouts/blocks/iphone
footer.php
head.php
header.php
main.php
mainnav.php
menu.php
toolbar.php
This also did not fix. Template is working fine in safari, just full screen view, not single column for iphone.
Will get back to you when I get a fix.
Another item of note. The site is currently offline in the Joomla control panel, however when displaying the site with an iphone it bypasses the standard login screen.
