Data usage issues with iPhone 4s?
I just got an iPhone 4s yesterday and I've been monitoring my data usage to get an idea of how much is used for various uses. My Verizon account online says that I've used approximately 18 mb, and the free app "Data Monitor" also says something similar (16ish), but the built in data tracker in the 4S (General - Usage - Cellular Usage) says that I have received 1.9 GB and sent 660 MB... How is this possible, I've literally had this thing for 24 hours. The only thing that I used cellular data for was to occasionally check e-mail and stock quotes. Everything else I have done in my apartment over wi-fi. I upgraded to the newest software available which took a significant amount of time, but that was done in my living room and was definitely over wi-fi.
Anybody experienced this or have any suggestions as to what may have caused the usage tracker to say 1.9 GB was received, even though this does not match Verizon by a long shot?
iPhone 4S, iOS 5.1.1
