There have been sporadic
and inexplicable reports, which no one has ever duplicated in a testable manner. Personally I suspect the user(s) in question accidentally tapped something.
If you don't want to jailbreak, why do you care about the updates? Anyway, I don't think there is any way... aside from dumping a few gigabytes of info onto the userstore so there isn't enough room to download a +150MB update.
