Sorry if this bug has already been reported before.
The first day IOS 8 appeared I upgraded my iPad 2.
Then suddently, when writing a post, it became frozen at a certain point.
No further writing possible, no backwards to the previous page, nothing!

The whole display was frozen and the only way to get out was with the Home button to finish Safari.
Luckily I found in the web instructions how to downgrade to 7.1.2 and at least at that moment (September 23.) it was possible. Today I do not know if downgrading is still possible. Now, in spite of IOS 8.01 and 8.02 I will still wait for a while. A frozen iPad is a scary possibilty and I do not know if downgrading will still be allowed by Apple if the newer IOS version causes the same problem,
If any owner of a iPad 2 had the same bug and if IOS 8.0.2 solved it,I would be very grateful to tell me about it. Thanks ! Ed
