I`m searching for program who could create next application.
This is console app for *nix. It should be able to do next things:
- check phone number or email for iMessage service;
- send text and photo via iMessage;
- check status of sent message.

Programming language isnt important, but I would ask you to send me sources when you finished your work.

May be it is very hard to create such app for PC so I could suggest you another way.
You could develop app for iPhone with Jailbreak. And then for example run this app via SSH from PC.

I`m ready to good price for this app. Contact me via pm.
