If you want to use the iPad on AT&T's network, it needs its own plan. Data plans are not shared between devices.

I believe tethering is $20 a month more than the non-tethering plan.
tethering is 50.00 for 5GB

So if I have unlimited data plan on my Iphone4 can connect to a Ipad
No, to add tethering to your iPhone, you loose your unlimited data as you need to go to a plan such as the 3GB data plan.
