As I said, this isn't a real solution, but it isn't all that expensive to increase your data limit these days.


I notice you said that she always switches to Wifi when it's available. Does she also turn off her 3G data when she isn't using her phone? It can be a tough and self-limiting practice to start, but at least it may limit the data usage of the apps until we can figure out what is causing the bizarre amount of data being used.
Finally, is there a particular reason that she doesn't want to root the phone? Once rooted there are loads of other solutions we could look in to, such as installing a custom ROM and seeing if it makes a difference.
