There must be some sort of caching problem. I find that both Safari and FB can open pages a few times, then they will crash. Sometimes I get Java Script errors on the debug panel, but mostly I get a message saying that the browser can't connect to the Internet. Settings show that the device is connected to Air Port with standard settings. Usually, if I just wait a while the problem clears, but sometimes I have to connect the iPad to my iMac desktop. Syncing seems invariably to clear the problem. But when I disconnect and try to access the Internet--it doesn't matter what URL I use (Google, Apple, etc)--the problem recurs after a couple of hyperlinks. Sometimes, clearing cache or resetting network parameters will also clear the problem--apparently--but not always. I'm confident the problem isn't an Air Port problem per se, since I have an older iPad that can still connect even when the iPad 2 can't. I haven't tried connecting via 3G--I haven't subscribed yet to a plan. Summary: this doesn't look like a Safari or FB problem, rather it looks like some sort of caching issue within iOS; I can't tell whether it is specific to iPad 2. Apple will have to address this quickly or else it will lose many customers.
