How much is your AT&T bill post iPhone?
 

I'm curious about how much people now pay on their lines; I've estimated close to $80. Let me know what you have as well. TIA

my bill went down when I added the iphone.

understand you are adding a data plan. I had a pda connect plan at $50/mo and when I switch my cost dropped $30/month. Over the two year contract thats $720 saved.

edit:
actually its more, because w/ the $50 pda plan it does not include text, so I was paying an extra $10....total savings $40/mo ($960 over two year contract)
