I just stumbled onto http://pdadb.net while looking for some info on a particular mobile device. They claim to have the largest mobile device database.
It's a pretty cool site if you needed to quickly lookup any specs on a particular device.
Example:
http://pdadb.net/index.php?m=specs&i...ei_ascend_m860
Some mobile advertising networks might list a device targeting option as
"Huawei Ascend" while the other might list it as the "Huawei M860" so this site could be helpful for figuring out what model number is a particular device.
You could of course also just search Google for the specs but this might be an easier one stop shop...
WURFL for the win... why because thats what most people use.
