iOS 6 a Data Whore?

I have a measly 1GB monthly (blame Rogers, we Canadians really get screwed in terms of telecommunications), and before iOS 6 went live, I was perfectly fine with data usage (being moderate). Now, no matter what I do (Wi-Fi whenever possible, reduce syncs, etc) I've been hitting my data cap just over half way in to each month. Is anyone else having this problem, and what have they done to solve it? Cheers!
