On: iOS7 is not about flat

[Angostura]

My concern is the ability of apps to eat all the data in my data plan without me knowing.

This would be my biggest concern too. Due to the huge cost + tax of data plans here in Canada, I'm only on a 1GB per month plan :(

I would need the ability to completely turn this off - which according to another comment here it will be.

Don't take this flippantly: have you checked to see how much data you're actually using?

I did when switching carriers and was shocked at how little non-wifi data I was really using. I use plenty of apps, get they typical corporate load of emails, upload photos, read stuff on the internet... and my cellular usage was in the low hundreds. Which made sense thinking about it, wifi at home, wifi at work.

Yes, I actually do keep an eye on it, and have the limiter set on it. My phone (from the UK) doesn't play well with the networks here so I am restricted to EDGE :( Just about to buy a new phone so with LTE will get much faster speeds. I used up over 400mb this month on EDGE, with very restricted usage. Once I get full speed I know for sure I will use it more. My wifi usage is pretty high, 3-4GB per month. I would regularly use up 2-3GB month in UK due to YouTube and streaming music.

Last time I checked WWDC slides it only does this when connected to Wi-Fi.
