Have them both activated. Your BB will switch between the two depending where you are. When you're at home it will use the WiFi network as the signal is more likely stronger than the mobile one. When you leave the WiFi area it will automatically switch back to the mobile network. It's how i have it set up as for some reason the 8900 can't pick up a great signal from the mobile network in my house (never had the problem with standard mobiles).
