After I updated my iPad1 (I know it’s not the latest apple device, but I’m not an apple fanatic ) to iOS5, and later to iOS 5.0.1, I noticed that was really slow in the normal usage and applications crashed almost once every hour. At the end I had an iPad but it wasn’t a pleasure to use it like the past.
After some tests, I start looking for something to fix these problems, knowing that Apple doesn’t allow the downgrade to old versions. And the solution I found, that seems to work after some days of tests, is to reset all settings, going to:
settings -> general -> reset -> restore all (maybe in English the menu names are not exactly these, but my iPad is in Italian )
With this reset you don’t lose your data (applications, photos, musics, mails, …) but it just restore the iPad settings to factory default. This means you have to re-enter your wifi key, you have to select your backgrounds but nothing more. An important thing is to prevent restore of these settings from a backup. In fact, after restart, iPad ask you to enter some settings like the first time you start it up: language, location, etc… And then it will ask you if you’d like to restore the device using iCloud or iTunes. Well… Here you have to say NO
Right now, my iPad works like with the previous iOS version: not slow, no apps crashes… At the end I have my iPad back.
Hope this could help someone else.
