I read the following which does not help much: S60 Platform: Web Browser Product Description. It is a brilliant document if ever you need it, it simply didn’t answer this specific question for me.

I don’t really have much more time to spend researching the problem, so I thought I’ll try to crowdsource the answer… Hopefully someone has an answer, otherwise I’ll have to digg deeper :( Trying my luck and being lazy! ;-)

UPDATE:
The content of the cookie is 1

You would probably run into this if your domain name is something like http://afrigator.mobi, without the www. or m. (i.e. without a domain prefix). The issue is that cookies for a specific domain are specified like:

//Cookie domain
$domain = '.afrigator.mobi';

A phone like the Nokia 6110 Navigator (its the phone I use, but there may well be lots more) is looking for the domain prefix (the www. or m.) and fails to store the cookie if none is present like in the case of http://afrigator.mobi

A pain in the butt which you might want to be aware of! The solution? Add a prefix should work. Downloading and installing Opera Mini could also work (although, I’m speculating since I have not tried that, but will soon enough). Anyone know of any other solution?
