Numbers not retaining data on iPad iOS 4.2

This is an issue for iPad running iOS 4.2. Numbers can not be retaining some entries after you close Numbers app. And it also delete entries while working in spreadsheet. That happens fairly randomly.While you are modifying one cell within a column, the data in another cell within the row will disappear. Any data entered with the last update is not stable and makes the app useless. Temporary Fix
