This may be a potential solution to the problem people are having with MobilePress not maintaining the correct site view for mobile/iphone devices vs regular "PC browsers". I am by no means connected to Aduity and have nothing to with MobilePress. What I am suggesting seems to be working for me, if it breaks your code/site, you own all pieces.
In the folder wp-content/plugins/mobilepress, find and edit the file mobilepress.php, around line 59.
Look for the comment that says "//Start a session.."
Right below that comment, there's a construct like this:
if ( ! session_id())
{
@session_start();
}
Make this block look like this instead:
/*
if ( ! session_id())
{
@session_start();
}
*/
(you have effectively disabled that code by "commenting it out").
Save the file.
Try your site -- clear all caches on both the server (WordPress plugins if you're using any caching add-ons) and your client (browser, smartphone, whatever).
