ios 7.1.2 update used up all my data
I updated to IOS 7.1.2 on my iPhone 5 and all my data usage for the month was used up! At the time of the update I was connected to Wi-Fi and the iPhone was connected to my desktop with the cable. I called my service provider and they told me that I must change "cellular data" in settings/ cellular data to off, otherwise it uses both the Wi-Fi and phone data. This is outrageous. My suggestion is; don't update.
