Re: iPhone 4s excessive cellular data usage

I've the same issue 90% of my data plan gone within 15 days. I was with AT&T and Apple for an hour and all they have is execuses.

AT&T says that the 4s goes into sleep mode and drops the WIFI connection. And any updates are done over the cellular network. Why the phone connects via 3G when it has a WiFi conn. available ? they have no answer. 

All they say is turn off cellular data if you don't want that to happen. How dumb is that for a smartphone ? 

This is very frustrating, I am considering returning my phone if in a day Apple or AT&T won't fix this issue.
