Here's what I did that I read in another thread that appears to have worked for the time being:
1. Go to settings-->Safari-->Clear Cookies and Data
2. You will get a pop that asks to you confirm that you would like to clear cookies and data, do it.
3. Restart your iPhone by holding the home button and on/off button UNTIL THE APPLE LOGO APPEARS ON THE SCREEN. Don't let go early.
4. If not connected to wifi, connect through settings menu.
Again, this fixed my problem but others are reporting that it did not work for them. Good luck and hopefully Apple will get a patch out ASAP.
