The New, Old, Mobile Device Capabilities Tool
Just a quick note — The device capabilities browser we were once hosting on devices.theoreticlabs.com has been moved here and given a new life: http://mobiledeviceinfo.com.
You can filter the list of available handsets by screen dimensions, MIDP version, ringtone or video support, model, and brand. We also made a couple updates to the tool to divulge a little more detail from our favorite free handset information database, WURFL.
Enjoy! And feedback is always welcome.
