I have iPad 2 & iPhone 4s and when I use Safari for more than about 5-10 minutes browsing web pages, usually but not always multi-tasking using tabbed browsing, it crashes regularly, sometimes every 5 minutes, on both of my devices. Safari will just close & goto my home screen. When I go back in, it has to reload any tabs I had open. Anyone else seeing this? Has anyone reported to Apple?
