I have almost gone over my data limit..funny thing tho..I've not used 3G anywhere. I've been at home, connected with my WiFi...I barely even make a blip on my data usage (1gb) read a ton of stuff about it...apparently it's a common ios 7 issue???? what's the point of having WiFi??? It's idiotic...the best answer I got was "to be safe" turn off cellular data when your on wifi...um...yea..no I'm curious..the only reason I found out was from my text alerts...what the heck???
