How much would an iPhone 4 cost with Att?

I'm just looking into things, but how much would an Iphone 4 cost with unlimited text for sure, and if there's an unlimited data plan, that too? I rarely use calling, so about 20 minutes a month would cover me there.

I would like to know the cost of:
-iPhone 4 (isn't it $0.99?)
-Activation fee
-Unlimited text
-As much data as needed (How much is MB and GB?)
-about 10 minutes of calling per month

Where can I find this information if it's out there?

Finally, If you don't like the iPhone, why not, and what is another affordable touchscreen phone that has internet, apps, and a good camera?

I assume you don't have a contract, which is a good situation to be in for getting a nice phone cheap.

Call ATT and ask them. They can often get you better deals when you call like no activation fee, and that sort of thing. ATT is $30 for 3 gig of data. Figure about $60 a month for what you want. I don't think there's any calling plan with only 10 minutes.
