Look in options, mobile network on the device. See if there is a way to force or set a preference for wifi over wireless. On UMA devices like the T-Mobile USA 9700, the user can set wifi-only, but I understand that is UMA devices only. I believe with the proper setting your device will prefer wifi over wireless, but I don't know the setting.
Also, if you look at the icons on the screen, if you see GSM, you are only conntected to the voice network. But if you see any of the data connection icons instead of the wifi icon, then you are connected to a data network and possibly subject to being charged. (Be aware that you may be charged for data transmitted and received over the wifi network. Or maybe not. That is why I say talk to your carrier.)
For information on the icons, see the following: Re: What do these berries mean? - T-Mobile Community Display Screen Icons (BlackBerry® Bold 9700)
