Is there an app to check who you can call for free?

[whoopn]

Hi I'm new to the Iphone scene and I would like to know if there is an app out there that will go through your contacts and check to see who you can call for free (they are on AT&T) and who you cannot. I'm not look for Skype or anything like that...I want to know who I call for free and who I don't.

I know AT&T's wireless webaccount can do this one number at a time but I have hundreds of contacts.

Thanks in advance!

unfortunately you cant right now unless you unlock your phone and then you lose your warranty... i would wait until the update comes out in juena dn then wait and see if a developer can create some sort of app but it seems like the only way this would happen is if apple decides to implement this into the new software update....
