I am running a BB 8110 and have no data service, so the browser is really unnecessary to me. It does nothing other than eat my RAM (if that's how it works), and take up a spot in Application Switcher.
I've looked on google and the only thing I've found is the obviously stated "uncheck browser" - however, I am trying to install the new .102 OS and the checkbox for browser is grayed out. Is there any way to bypass this?
