"Here we go again. Every major update causes suspicious slowdowns in older iPhone and iPad types."
There may be updates to fix issues that folk have on older pads but at over 3 years a lot has changed in CPUs and more. The only good news is your pad is still working.
OK, https://www.google.com/search?q=how+to+go+back+to+ios7+ipad+2 seems to find how to go back.
Jumped the Gun and Updated to IOS 8 on my ipad2... Learning the hard way, should not have been so eager .. Should have waited it out .. Aside from occasionally Freezing up when composing an email.. YouTube , should I wish to advance while watching a video to tap the white dot can be an exercise in futility.. Once I've found the sweet spot if you will drag the dot along , but then sound & continuience hangs up..What's Wrong... If there was a quick and easy way I could Erase or Revert back to an earlier date to my original IOS 7 I'd do it in a New York Minute, problem is I suffer from the Fat Finger Syndrome and sometimes dig myself deeper . Help would be Appreciated, Cheers Thanks
