What's the price of the cheapest Iphone?

What cheapest plan that consist unlimited texting, calls, and internet(optional)? How much is the phone?

Right now with T-Mobile you can activate with now contract or activation fee or upgrade fee and pay about $76 for unlimited talk text and 500mb of overage free data. That price includes the cost for the iphone, taxes and plan. $50 for the plan then $21 for the phone and about $5 tax. Honestly I think that is your best bet

An iPhone ranges from $200 to $400. Verizon has all the things that you're asking for, with excellent general service for $80 a month. If that's too pricey, AT&T has decent service, and will do it for cheaper. If you're desperate, Apple does a cheapo plan as well, which will also mean you can buy the phone for less.

Virgin Mobile has plans from $35 and up.
