What's the best (easy&efficient) solution for asp.net developers to develop a mobile version of their existing website

Question

I hope the question is self-describing.

I'm currently developing an asp.net website which uses a MS SqlServer database in the data layer.

And I was thinking what are my options to get a mobile version (most importantly supports BlackBerry and iPhone and hopefully every mobile device!) and when used on blackberry I want to be able to let it run at the BB's background.

I was thinking about asp.net mobile controls but the projects page seems like a dead/not-updated framework and not sure exactly if supports only windows mobiles or what!

Edit Thank you for your questions, but they all covered my problem from only one respective .. I mean how this is going to let me use the BlackBerry Appliction options like letting my website run at the device background or sending notifications to my users!

This is mostly going to be a product of styling. Mobile websites work just like regular websites these days, except you want to use CSS and images that work well on a mobile device. You can use a product like 51 Degrees that will give you a bunch of information on what type of device is connected, so you can customize your output based on resolution or any number of other things if you so desire.

You could also try a book on mobile design, such as "Mobile Web Design" by Cameron Moll.
