touch on security swipe in the menu
type in "blackberry" and it will load the original software

Answer 1

I was about to the above and had even gotten to the point of having completed the full backup, when suddenly I tripped over what the real cause was.
Prior to doing the backup, I had checked if there were any software updates.  There were none.  But after I did the backup, suddenly there was an update available but when I clicked to do it, it said I did not have enough room to do it and had to free up some memory on my 16MG PB.  I removed some stupid videos my 9 year old had added in the past couple of days, and BEFORE I went back to do the download tried to open the browser one last time.  Now it finally was opening.
So if you have internet connectivity it seems, and your browser button is not greyed but simply won't open, try to simply make room on your PB if you are running what may be near capacity.  I can't recall what my numbers in the "About" "Hardware" screen were prior to deleting data, but now after removing about a dozen photos, and deleting about 4-5 minutes of video only, it now reads 
Total Storage: 14.6 GB
Free Storage:  104.6 MB
Free Memory:  306.3 MB
I'm gonna delete some more stuff now in my music stored.  Certainly do not need all five versions I have of "I Can't Get no Satisfaction". lol.
EDIT:  I should also mention that the other symptom I was getting is that I could no longer bridge my emails and other bridged applications either.  I could open my Globe and Mail add-on program as well as check out The Score add-on, so along with checking whether wifi was connected, it was working.  It was simply choking on opening what was becoming programs that were too big for the size of memory available, but would not give any kind of error message.  The Browser would just simply try to open, and close 2 seconds later without rendering anything other than a black screen and the little arrow in the upper left corner sometimes coming on before going kaputz.  The bridging would simply freeze on a white screen forever of nothing until I would minimize it and X it away.
And as a side note to the reply from Tex Tucker, you can't do what you recommend if you can't get into your browser in the first place,  
That would do it, however the first thing to try is
1. Browser settings, Privacy and Security, Clear ALL
2. Restart the Playbook.
IF that does not fix it then do the security wipe
