mobile stopped working

Hi
I installed the files okay and also the API manually on joomla 1.5.26 site. Went to iphone and all working. I then pressed the link at bottom to desktop and since then I can't get to the mobile version. i don't seem to be able to go back. nothing on ipad either.

since now there are 13 days and no reply to the trouble one is suffering ... quite strange this is where a quick support is expected...
