Right now the only mobile devices we use are Blackberry handhelds. The Blackberry Enterprise Server/MDS can be configured so it places the device's PIN (a unique number for each device) in the http headers. This can be retrieved with Request.ServerVariables["HTTP_RIM_DEVICE_ID"].
Do any of the other mobile devices, such as Smartphone, etc. provide a similar unique ID through HTTP headers?
