Check the headers that the phone sends. Some carry that info, some carry profile info and the profile tells all it can about the phone.

Hello andymoo,

You wrote " Check the headers that the phone sends. Some carry that info, some carry profile info and the profile tells all it can about the phone. "

can u please make it more clear that what header information contain mobile make (Company | Model ) and mobile no.

Actually i need to make sure that user from a particular mobile network (service provider) can access my page. other will see another page.

also i have to make a log of the users who visited my site & click on a link.

I am using PERL for server side scripting. & now need to detect which user is trying to open my page

if you lok at the http headers the phone sends your application you might see a carrier variable sometimes but not often. if you had your own wap gateway which authenticated the users you'd get a whole load more info.

screen sizes and so on is in the profile, if the phone gives you a link to a profile you can read the xml and pluck the variables or the other way is to build a database with the user_agent variables, screen size, content_accept variables and so on.

the cellphone number is rarely passed over as it's often viewed as an infringement on data protection and could open up a whole new world of sms spamming opportunites

re logos, just check from the headers if it supports gif or jpg and offer a couple of different sized images based on that.

Sir,
then how i can identify & log that a particualr user come to my site , request to download . is there any way to identify him.

Another question is how to provide option for JAVA games. I don't know what is main difference in .JAR & .JAD file. as i think for PC applications .JAR is java compiled archive which is an application run by jvm . In sense of mobile is it same

Waiting for answers
