I saw a new app called Agile Reply which allows you to send a sms to the person whom just called you. I didn't buy the app but I don't understand how it would work since as far as I know you can't access the call log through the official iPhone SDK. So my main question is:
Are there new API's in the iPhone SDK which allow you to access the iPhone's Call log?
I know there are similar questions here and here however I didn't know if I should hijack those or start a new one.
I found the solution here but it doesn't work for iOS5.
