When you have 2 small children asking "can we play yet?" the last thing you want to be doing is listening to them repeating it for hours and hours

it was bad enough having to wait for the 133mb upgrade it needed to do because they sat there watching the numbers going up
So if there is no other option than do to the 8gig thing, how do I do it afterwards? And will this garantee the end of the signing in problems?
