We are looking to turn off our home phone which of course feeds our internet to our comp. Phone at home is about & internet is about . What ATT/Cingular Phone do I need to purchase in able to be able to surf the web every now and then? I don't really know what rate plan I am supposed to be looking at? How about data plans? And what kinda stinkin phone do I need? One of those SMART phones? Please help. I'm not real cell phone knowledgeable.

Thanks
