Hi,
I'm beginner with BlackBerry so maybe my question is stupid

I have BB 8800 v4.2.1.74(Platform 2.3.0.54). In my device doesn't function browser (msg> Your Device does not currently have any Browser Configuration Service Book Entries.) but my old device BB 8700g already function. My question is: How re-install BB OS on my device or something other how enable browser or more likely Service Book Entries.
Sorry for my English
Thank you for help
Stepan
