I am trying to decide between a Blackberry PDA and an IPhone. I want to be able to access the internet all day with a good internet browning experience. I would love your thoughts regarding PDAs or the IPhone for internet connection. (or any other suggestions you have for a small portable internet connection)

I thought about buying a Dell Mini, but internet access would be $60 a month which I really don't want to spend. Cell phone internet would be $30 a month.

HELP!
