Hello,
I am to build a new DNN website that supports browsing from mobile phones / smartphones, and  to evolve another already existing site for which I am to add support for mobile browsers too.
I don't have experience with this kind of devices, is there somebody willing to share some info or best practices?

I think I should be able to differentiate loading of css with regard to the kind of browser (the minimal entropy skin has something specific for IE, isn't it? would this mechanism be helpful?), but would this be enough? Or would it be better to build a separate website / pages to serve mobile browsers? And how to handle redirection, with some custom module?
Also, I imagine "mobile phones and smartphones" is too large a category, that is I'm afraid there's a need to build different css for different kind of devices (windows smartphones, iphone and blackberry for example), is this true?

Thanks for any help,
al.

Rodney,
thank you for your precious help. So you have this page (mob.aspx) to serve mobile content, but is it all a matter of skin? You don't have neither custom content nor custom modules to serve content to mobile browser - that's a normal page with a "mobile" skin - , am I right? 
Sounds cool! Are you automatically redirecting mobile browser to this page with some custom module, or just tell them to go there?

Thanks again,
al.

Yes, it is a page on the same portal (it has to be as some of the modules do not allow data sharing across portals, and it makes life a lot easier having one portal only) with a scaled down skin (check the mobile doctype at the top). I then added skin object CSS removes to get rid of default.css etc. I don't need any of the core stuff - just the mobile skin .css (you can do a view source and see it all).

There are definitely more elements that would be nice to be stripped out but it's down to 4k which is pretty good (and it looks good on the iphone). I DO have custom modules (the league module is my own custom module) - and I do a separate mobile version for it (a new .ascx) file as it is completely different to the full version (this is a matter of preference, but I strip out all AJAX and extra columns etc.) - I think it's important to design the app how you want it to look on the iphone, not take the existing one and try to force it in. It depends on your site though - if it is just static data you just need HTML mods.

At the moment my skin does not do any redirecting and you can switch between full and mobile on the web or mobile browser. I raised a thread a while ago about detecting the user agent and redirecting to the mobile version - it's not hard (Timo is working on some skin object to do stuff like this I believe). I just haven't had time to work on the mobile site again (I would suggest they use the mobile version but not force them - if they want to browse the full site on their iphone then they can (so it should look ok) - my mobile version is an app (you can add scores from the poker table) - whereas  my full site has a lot of data, forums etc. It depends on you..

I am very keen to see Steve's presentation as it sounds really interesting! Unfortunately I wont be able to attend in person or online - I hope it is available for download after?
