Facebook redirects Konqueror to Facebook mobile; I assume it sees WebKit and thinks IPhone. Until facebook corrects the identification error, you can use Konqueror’s settings to fix the mistake.
Navigate to http://www.facebook.com/facebook?ref=pf.1
Go to Tools > Change Browser Identification > Safari > and click the highest non-IPhone version you see. (On my computer, this was 3.2.)
Enjoy lightweight browsing.
- The setting we are changing will be applied to a domain. Since you cant get to facebook.com otherwise, you visit this page so that the modification is applied correctly.

Tnx for the info. Strange that facebook gets this wrong. With 400M active users on facebook, a 0.05% konqueror usage, that is 200 thousand people redirected incorrectly!
On my Konqueror (4.2.2) there is no ‘Tools’ menu. In “settings->configure konqueror->browser identification” it is possible to make the same changes though.
Thanks, Hugo.
