Help high data usage

[dishfreek35]

Hi, I just purchase a nexus S for wife because that the phone she wanted, now 1 month later we found that it's using a lot of data on 3G signal when she's not even using the phone, seems to me that it could be downloading updates of some kind all the time, is there a way to control the updates and other stuff to operate only when the phone is connected on wifi?

Or you can turn off the 3G all together when on wifi. Here this works great.
