i am developing sites that needs to be formated for mobile devices. because i don't have all the devices (like iphone, android, htc, evo, blackberry, ipad, nokia etc...) i would like a tool (like http://www.deviceanywhere.com or similar) that can simulate a phone and then i can go on internet to see how the website looks like.
is there a tool like device anywhere (which is expensive for me) that can do this?
Tools can be on Windows or Linux
edit: i have a budget for this, but free is better!
