well the iphone with any 2 year plan is 199 for the 8gb or 299 for the 16gb. a basic phone plan would cost around 90 dollars for a good amount of minutes. unlimited texting would cost twenty dollars. you could get medianet (internet) for it, but why? it has built in wi-fi so you really don’t need that. if you do want the medianet service it would be about 25 dollars. so if you add it all up…

8gb = $200+$90+$20= $310 ($335 with medianet)
16gb = $300+$90+$20= $410 ($435 with medianet)

monthly you would pay between $115-$140 with all the things i said.

hope this answers your question well enough =]

I agree with *Ironham*, it costs nearly $90-140/month depending on your needs. It’s a little costly but if you’ve a present plan with AT&T or T-Mobile, then there’s no need to spend all those and use the present service with the unlocked iPhone. If you need unlocked iPhone, you can mail me or talk with me on Yahoo!
