Hi, I still have the problem. I'm ready to buy new iPad but also want to sell iPad1.
The problem came up at one point and occurs in ANY app! It seems that whilst I am active in the app (like bringing apps up to dat in app-shop) in works, but asa I have the slightest pause, it crashes (goes back to homepage).
I tries all the above. Also re-installed it completely.
Noticed now when I did most again that the multi task bar had a huge amount 25 ? apps open simultaneously !!!
But this was not the reason for the crashes - which persist
!!
