I need a new PDA or SmartPhone with WiFi? - smartphone wifi

I am in need of a PDA or a smartphone for work / school. I need a wifi with it.

Which phones have wifi in them?

I am not speaking of cell phones with Internet access via a wireless network, I mean connect to any wireless network that I want.

Thank you!
