It is amazing to me that this is still a problem. I have been calling in to customer service every month since July 2012. Why? Because no one still knows how to solve this issue. Their "solution" is to just turn my cellular data off while at home. It isnt supposed to be using my data anyway when I'm on wifi and seriously what a pain. AT&T blames Apple and Apple blames AT&T- the sad part is, who is the one getting the raw deal.... Oh yeah "raises hand" remember me, I'm the one paying for your service .... The CUSTOMER. Horrible. (Oh, and from doing some more research, they can't blame just Apple anymore- this is happening with all types of phones they have their data service for.)
the decision to utilize wifi or cellular is made at the device level, and at the app level, no carrier has the ability to force a phone to utilize cell over wifi. The switch back to cellular is automagic, if your wifi connection is bouncing the phone will switch and stay until the wifi connection becomes stable. By design a cell phone when it goes into hibernation mode will turn off the wifi radio if not plugged into a charger., if you have an app or apps in the background that auto update information - like email, facebook autocheck, twitter or any one of the other thousands of apps out there that multi-task and run in the background they will use cell data - this is universal.
As an experiment I took a iphone and a HTC Inspire that was not in use by anyone in the company and reset it back to factory defaults, nothing installed outside of what the base factory apps
