BB Curve :: 8530 Phone Won't Connect To Webpages

My BB won't connect to webages. I try typing in address and try using google, neither one works. At the top is says, for example, www.mfacebook.com t starts to search it and load it but once the bar is full it does nothing and the screen is blank. I checked out connections and there is a green checkmark to the left of WiFi but then in the box it just has a white line. Is there something wrong with the phone? I took out the battery and it still doesn't work. how do I make sure everything on my phone is updated? Everytime I ever plug it in to the PC, it ALWAYS says "there are no updates" which seems odd? It's a Curve 8530 andI have had it for a year and a half.
