C#/C++ code to grab SMS messages backup from iphone

I want a small win app that will allow you to run it, it will connect to iphone and pull the SMS images and messages from the phone. Basically I want something like "CopyTrans" has. I want code to be c# or C++ to drive this. Data should be copied to local SQLite file. Images can be copied to logical file system and referenced by the SQLite tables. Please check how CopyTrans works, of many apps it seems to be consistently stable. This code should be well commented, We will be using it as a library in another larger application so we dont really care about UI for customers, we just need the UI to support testing the core code. Things like progress or status should be clear. I dont mind if you use console windows for this sort of thing. I just need it to be detailed and if it hits and error i need it to fail gracefully and with error details. I dont know what this might cost but looking for a good value, most importantly i need stable code
