cellular

How do I tell if my new iPhone is using wifi rather than my cellular data plan ? I know it's connected to my wireless router at home, can see that on the wifi menu. But the AT&T logo and signal indicator are always showing even when I'm just web hopping. Will these always use wifi if...

FYI! All U.S. cell phone numbers are being released to telemarketing companies tomorrow and you will start to receive sale calls. YOU WILL BE CHARGED FOR THESE CALLS to prevent this go HERE and register. Cheers all! Chris
