Oh yeah... Never had this problem when in my home country, but now I remember seeing this once when in Germany when I had disabled automatic internet connections. I accidentally opened twitter from the feeds screen and got a continuous loop asking me if I wanted to allow internet connections. I kept hitting no, but it kept asking the same question.

Quickly shutting everything from the multitasking screen stopped the loop. Annoying as hell.

Never happened with automatic connections enabled.

Edit: Just tested this. Easily reproduced. Happens every time. Is this in PR1.2, too?

Edit2: You can get out of the loop by answering "yes" (prompt opens, doesn't connect to anything yet) and then closing everything. No need to reboot the device.
