OK, I did a search here and could not find the answer to this question
what does "start blackberry connection" option in the browser do?
clicking this option while browsing any website does not do any thing.
anyone has a quick answer?

I believe this just switches your browsing back to edge instead of the wifi connection. The only time I see that option available is when im browsing over wifi.

I don't see this option with my (non wifi) 8310.
