Browser String Issue

Hey everyone, I have an issue in which I am trying to download an app from a website but it only supports the "Blackberry" web browser string rather than the "Blackberry9530xxxxxxxxxxxxxxxx" string that the Storm's new browser is using. My question is, is there any way to change the string that is sent out to the internet to just "Blackberry" like the old ones used? Just cut off the end of the string since some sites only look for the short "Blackberry" string to know what sort of file to give?

Thanks for your help.
