my iPad mini 2 was bought in Dec 2013 I did not update the iOS since then. The version is 7.0.3 I had NIGHTMARE with my fully-functional iPhone 4S. I updated the iOS last year, it became extremely slow and lagged and then rendered useless..... Is iPad mini 2 now too old to update the iOS? I know once it updates there is no turning back the clock so I am looking for the most honest advice Than k you!!!!
