why does my internet not work on my blackberry bold but it did on my old blackberry

8250? i used to have a blackberry curve 8250 and i could go on facebook, trainline google etc without having the need for wifi sign in or anything. now i have the bold and i can only go on facebook. it says a wifi connection is needed for google etc. this is so annoying as it didnt happen with the blackberry curve which is meant to be a worse phone. i understand that if i log into a wifi place then i get google and all. but i didnt have to with the blackberry 8250. what can i do?? and why is this happening?
