What's the cheapest AT&T iPhone contract monthly fee? I don't like overpaying for cell phone service, and my usage is usually quite light. I'm currently with Verizon but if the iPhone 4 Verizon rumors don't pan out this year I'd finally be interested in switching.

Cell Phones and Cell Phone Plans - Wireless from AT&T

Looks like $35 for the phone and $15 for the cheapest data. Also includes no text messages.

Family plan can lower that even more. I have the cheapest plan + unlimited texting, which comes out to ~$32/month (albeit with a student discount, which only reduces my bill by like 5%).

If you are old, they have a senior plan for $29.99. I'm lucky in that I still have a plan I got back in 2003 .... 250 minutes with 5000 NW. No mobile to mobile or rollover minutes with that but I've only exceeded my minute limit maybe 3 times in 7 years (and even then, not by enough that it cost as much as the current lowest plan). With the $25 data plan and $15 messaging plan, I have a base cost of 69.99/mo (up from $59.99/mo that I enjoyed with the original iPhone as 2g data + 1500 messages back then were bundled at $30/mo). Still, pretty cheap total plan for an iPhone 4 and with skype and other means of voip calling, the minutes of my plan become less and less relevant.

Probably the cheapest (legal) way to have an iPhone plan is to be added as an additional line in a family plan:

$9.99 a month as a second line for sharing minutes
$15.00 for the cheapest data plan
$0.00 for no texting

$24.99 a month.

The only caveat is you need to find a family member willing to add you on and find a way to pay them. Also you have to "live" in the same state as them, but online when ordering AT&T will let you register your contact address in one state (your family member's home address in this case) and ship it to another state.
