can't browse with my cingular 8525 wifi over a non secure open network

How can i configure my cingular 8525 wifi to automatically non secure open network in public places so i can browse?
Most times i am in public places where i can browse with the wifi on my laptop but i cannot browse using the wifi on my cingular 8525.
Sometimes it detect available networks but i cannot browse with it.
I find it puzzling in that the same network with which i can surf the internet on my laptop dell 640m can not be used to surf via my cingular 8525.
What might be the reason?
Any help and suggestion on how to go about it
thanks
