Well, the choice should still be available. Default, the cap could be ON, so you can't download over 100MB via cellular. Then you have the option to turn that restriction OFF. Include the warning after you turn it off, "This will use data from your cellular plan, do you want to continue". Something to give us the choice. I can be away from wifi all day long and have to wait to download updates, apps, etc. I strongly dislike that. I've been keeping the faith that Apple will eventually give us that option, or have relied on jailbreak. I'd rather it be officially built into the iOS instead of me having to remove the restriction myself (j/b).
